2 things , iso 4000 and f29 , are way out . F16 , iso 1000 , and anything above 1/ 125 is fine . you are at wide angle , motion is not hard to hold . I have never shot RAW .If the shot is that bad , nothing will help .Also at time the scene/ weather / light is not good , nothing will help . Maybe try b/w .

I plead guilty for not reading the OP post carefully. I just notice now that the OP was using a Z9. So I have a question for the OP. You said the scene looked amazing but when you took the shot it wasn't. So did the scene look amazing when you look thru the Z9 viewfinder or did it look lousy?

If this is a typical scene for you, I agree that you don’t have an eye for landscapes. There are plenty of books available to give you inspiration, plus videos on YouTube. Most photo clubs have a show and tell session where constructive criticism is offered. There are some guidelines for landscape photography which I won’t go into but you need to learn what they are and practice practice practice. Digital film, as they say, is cheap. And the number one rule is that it’s all about the light.

When shooting landscapes, try having a center of interest at one of the four intersections of your grid line, you should be able to put grid lines on your screen, look in your manual. You will see two vertical lines and two horizontal lines, place your center of interest at one of the 4 places where the lines cross each other.
Personally, I like to shoot foreground background, in other words, have a foreground subject against a background.
There are many many ways to shoot landscape. DO NOT GET DISCOURAGED. Keep on shooting and looking at images you like, ask yourself, why do I like them.
Also, I strongly suggest you google this, "rules of composition for photographers", up will come many videos and suggestions, they are NOT really rules, only suggestions for use.
Good luck and keep on shooting until the end. Below are some of my examples from our Iceland trip last year.
The fist shot I used the colored bricks as "Leading Lines" (composition guideline) to guide you to the church in the background. The last three are examples of foreground, background. I used a Nikon 24-120 on that trip, the shots below were all taken at 24mm.
Good luck and keep on shooting until the end.

Composition first F29 is high

What were you expecting to see or obtain in this this shot? There seems to be no point of interest, except possibly the layering of the landscape elements (water, marsh grasses, distant tree line, and sky). You could punch up the color a bit, dehaze a bit and burn in the sky a bit to see if there is some detail there. Or replace the sky altogether with one having some cloud detail.

Consider some of the advice available at this site: https://photographylife.com/landscapes

and emphasize how to visulize the scene more than equipment used for the time being.

I set my ISO to 200 and expose for the sky if there is color. I estimate the hyperfocal distance for the lens and set my focus point manually or pick an object I can use single point to focus on. The ground will be under exposed but the D750 sensors dynamic range lets me pull up the foreground with Lightroom. Best of luck

I agree with what many others have previously stated...

I don't see a subject.

The foreground is not in focus. The sky is "blah". The background and the birds are too far away to be the subject so, everything in between simply makes this a snapshot, not a photograph. Unless you are Randall Hodges, it's hard to see why you would use f/29 when f/16 may have been a better choice.

Just my opinion..... which won't even get you a cup of coffee.

The OP said the scene was amazing and I would believe the OP that the scene was amazing. However, of course none of us see anything amazing about the scene in the picture the OP took. That proved that the camera lies a lot even when the photographer didn't intend to. And thus the photographer can persuade the camera to lie to make a boring scene looks amazing in the picture.

I would NEVER shoot @ f29 ( diffraction/low IQ) or ISO 4000 (noise and low IQ ) in a landscape - OR anything else ! !

I have had many occasions where I saw a scene which was very pleasing, took a shot, and determined my image was total crap. Many times it is because I had no definitive subject. That's the first thing I notice with your image. There is nothing in the foreground to draw your attention. Likewise, there is nothing "different" in the mid range or the distance to draw a viewers attention. I have taken shots of a marsh which looked so beautiful. Then, the image looks like grass, grass, and just more grass. Try to find a subject to draw the eye, and have fun while you do.

I agree that there is not a 'single' point of interest in your photo; plus it needs 'framing', some object(s) to direct the eye to the point of interest. Usually something in the foreground. It can even be the blue sky, or clouds, or trees, grass or... Usually a single point of interest is no more than 1/9th of a landscape photo (note point), it may be a mountain that takes up 2/3 of the picture, again the rule of 1/3rds (diagram of the scene, cut into blocks of 3 rows with 3 squares, for a total of nine segments. And they can be in ANY direction, up, down, and angled sideways. Plus, groan, the rule is not set in concrete! Look at what others have shot, and what makes you like their photo, composition wise!

I think you should go back to the beginning...your beginning!...like an amateur . No raw...jpg. and try your auto settings as a guide.
Then go t manual. You'll see the immediate results in your Z9 viewfinder. Shoot and compare. Then go back to raw and your tripod. But I think you should restart with the basics !!
