Your "Perfect Cactus" is a Saguaro cactus, which is native to the Sonoran Desert, AZ, Imperial County, CA, and Sonora State, Mexico.
The Saguaro can grow to a height of 40-60 feet. Saguaro is slow growing; a 10-year old Saguaro's height may only be 1.5 inches.

A B&W version of this image would be interesting; possibly better.

Perspective distortion is the issue with the photograph, not parallax.

First: It is Giclee (zhee-klay).

After reviewing the following on Giclee, you will be fully informed on what you're looking to purchase.

Architect1776 got it! Parallax not the issue. Note:

Perspective distortion: Is a warping or transformation of an object and its surrounding area that differs significantly from what the object would look like with a normal focal length, due to the relative scale of nearby and distant features. Linear perspective changes are caused by distance, not by the lens. Thus, the Leaning Tower of Water.
.
Parallax: The way an object’s position or direction seems to change depending on viewing angle (vertical or horizontal). Back in the day, as they say, before the nearly universal use of digital SLR’s the relationship between view finder and lens images was slightly different on the vertical plane with a non-SLR; the lens, obviously, the dominating. Some camera view finders compensated for this. There were also lens compatible view finders for the camera’s shoe mount to compensate for parallax.
.
Try this: Stand or sit viewing a near object (view the top edge of your computer monitor with an observable line or object few inches behind the monitor), alternately move your line of sight up and down from your viewing position. Notice the apparent "movement" of the background. Now you're not relaxing, you are "Parallaxing".
.
Linear perspective: Parallel lines that recede into the distance appear to get closer together or converge.

Crop is not a bad word. As a matter of photographic fact, it is essential to ALL photographs. Think about, the first crop should be just before the shutters is activated. What? That is COMPOSITION. Identify the subject, then make the subject the photograph. Any negative photographic space (too much sky, objects tending to take one’s eye from the subject, etc.) should be, if possible, eliminated beforehand or after.
.
While constructive criticism, if civilly stated, may not be to one’s liking, it should be considered. As a noted photographer, I don’t recall who, stated: “Crop it, crop it, crop it!”
.
Take a photograph, not a picture. Put yourself in the place of an artist painting a beautiful plein air landscape. Would the artist include, or add an out of place object (e.g. Posted signs, trash receptacles, etc.)?
.
Consider: There are two with camera in hand, one who “snaps” anything and everything, giving little or no thought to composition, and one who carefully composes before releasing the shutter, striving to create an appealing photograph, even an artistic image.

Fill in the blank: Welcome to _ell!

Dell has a huge presence in the business/commercial market, where the cost of computer maintenance may not be a priority matter. Should Dell use proprietary hardware, maintenance of like kind hardware may be less costly than having to use several different sources for components.
.
Several years ago I intended to add a component to a Dell computer, for what or for whom I do not recall, which was a Dell priority part the cost of which was about double the cost of typical. I declined. Also, I came into possession of an Acer small factor computer with a bad mother board. The only source of a replacement was from Acer. New motherboard: the price of an identical new Acer. Bye Bye Acer!

You correctly referred to "Jackson" not "Jackson Hole" (It's Jackson, Wyoming located in Jackson Hole.)

Just kidding: I think it is "butte" not "butt". An elk's butt can be seen on the butte.

The "speed" of a computer is primarily controlled with the CPU. Other factors contribute the a computer's speed; RAM, CPU and HDD (or the faster SSD) working together determine actual processing speed. Therefore, coupling more RAM to a slow CPU will not increase speed; coupling a fast CPU with insufficient RAM - same result. Running several applications concurrently also affects computer speed.
.
Anything over 16gb is likely overkill unless you specifically know you need it (such as for video editing or audio post-production). For most users with a "fast" CPU, 8gb of RAM is usually sufficient, 16gb should suffice, 32gb - 64gb likely not beneficial.
.
The only thing that additional RAM does is allow your computer to do more things at once, not actually make it faster.

The "white & trees" are a distraction. Had the subject (girl) been positioned closer to the fence the background would have eliminated the distraction, the subject "jump-out" and no cropping would have been necessary. For this photo, too late now. Still a nice picture.

A recent User asked how it is possible to achieve the "Rembrandt" light effect of a photograph. This photograph on the FilmFerrania website posts an excellent example of this. I might mention that this technique is properly termed "Chiaroscuro" (Italian meaning light from and unknown source).

Chiaroscuro Example

No critiques on which to comment!

Forgot -
Your second attempt is getting there. Suggest: Darker background and fade light to darker on object. If you have a dark background cloth use it to eliminate sharp background elements. Try your list source is two or three different positions. Try lighting midway between right side and the back. It might be interesting if the left side of the model's head starts merging with the darkened background.

In my opinion there are two aspects to photography: One as a picture taking device for compiling person photo albums and/or to produce a personal artistic image. It should matter not if the viewer likes or dislikes your work. How many differing opinion will result comparing a Rembrandt to a Picasso?

It's a misconception that "pictures" are art. Don't accept criticism that post processing and cropping are a no-no. Be an artist, not a picture taker. Take chances. The object is to draw attention to thought-provoking art not pictures.

Experience: I was close friends with a watercolor painter, a well recognized artist, now deceased. A rural scene of his, in my collection, depict a red barn, windmill in background and sheep camp (wagon) in the foreground neither of which were located near the actual barn location. The point: Art not reality, appealing and not just another barn.
