Was expecting this suggestion: "expose for the highlights setting a narrow acceptance angle like spot"
But my takeaway from the other responses is that feathers can be a special case requiring negative EV, above and beyond.
I'll keep that in mind next time I get an assignment to shoot S&M products, in nearby San Francisco.

Simple; expose for the highlights setting a narrow acceptance angle like spot metering. Then while viewing the image on your monitor, you can brighten the under exposed areas in any one of the post processing programs.

A composition desideratum is to find an interesting or unexpected angle. The thoughtless composition would have shot the front of the open box. This is way better.
Like the out-of-focus foreground.
The two versions tell different stories.
It is hard for me to know when highlights are just right or intrusive. I wonder if a circular polarizing filter or a different angle from the LED source would be worth exploring.
What's with the mostly illegible Spanish-language text at the upper left? See magnified download. Looks like a hand-made label. Maybe Photoshop could reveal it.

Snakes. Was watching Lonesome Dove's water moccasin (That's a rattlesnake variant.) scene of pioneer Texas yesterday. Thought to myself, there were so many rattlers even when I grew up in Texas, what must it have been like nearly 200 years ago? My cocker spaniel contstantly killed them in our back yard. Easter egg hunts always prefaced with a productive snake hunt. Snakes swimming in flooded streets. ...
My worst experience was while swimming in Beaver Creek, which feeds the Llano River. I was sitting in an inner tube. Grabbed a bunch of tall grass on the bank to pull myself in and exposed a water moccasin coiled and sunning itself. Disturbed, it slithered into the water beside me. No point in trying to describe the next thirty seconds, but I'm still here.
We kids always debated whether these snakes can bite while swimming. We had to conclude they could not or we'd have never gone swimming.

You might out-design them and offer them your intellectual property.
Make a feature table that compares yours and theirs. Do something unique and critical, based on input from camera people like me. I see your effort as a good start on a workflow problem whose solution is worth money.

Here you go: https://www.manfrotto.us/catalogsearch/result/?q=cross+arm
What I did not say:
* Got a Bogen tripod for its crank center column; trying to figure out the mechanical fittings ... hoping to diddle the tripod legs less often
* The load gets bigger than you'd think so a strong tripod and head are needed
* A related issue is changing the camera (sensor) orientation conveniently, between landscape and portrait

I totally admire this. Your work is neat and it looks like it could be a commercial product.
A cross-arm is super-useful if you don't want to move your tripod and reconfigure it. I have Manfrotto's four-head cross arm and am not totally satisfied. Still, it is better than moving my tripod's center column from vertical to horizontal.
In your prior post you have your arm on a ball head. I'm in the minority of shooters worried about slippage. My commercial arm, attached to a tripod, has to hold a geared head (no slippage), a two-way focus rail, and a FF camera-lens. A counterweight would be good but I don't want to go there.

DC lenses are not a solution for problematic skin in portraits. These lenses retain subject sharpness and soften the out-of-focus areas, for a chosen DoF.
I've been researching the 85mm DC and 105mm DC as a possible buy. DC allows added control of the areas outside the area of focus. That is, you can further defocus in front of or behind the sharp focus the DC lens provides, regardless of aperture short of the whole frame being in focus.
Unlike the DC controls, a soft-focus lens -- Nikon has made three -- softens the whole frame.
On a lighthearted note, yesterday I saw a portrait of a woman, but the image had been photobombed by a german shepherd defecating in the background. See Dogtime.com, item 7. A DC lens could have saved this shot.

There is a lot of commentary here about apertures, focal length, and angle of view. It is often forgotten that getting close with Nikkor micro lenses can cause changes from the headline specs.
For example, the 105mm f/2.8 AFD is 105mm on FX at infinity and is f/2.8 at infinity. At macro distance, this lens acts as an 80mm focal-length lens. Likewise, the aperture becomes f/5 at life-size, courtesy of Nikon.
A note on my experience with my G version: At macro distances, you may find auto focus won't happen, especially if there is little contrast between subject and background. This is not a defect. Of course, manual focus comes to the rescue in this case. Sometimes the lens is unresponsive due to user failure to reset the switches, for example, from MF to AF.

Laughing, but it's serious.
My main tripods are Bogen and Manfrotto. That's not good enough. Think about it:
1. I'm installing 32 square feet of interlocking padded flooring squares today in my studio. A 32 sq. ft. area covers where things in use or staged -- not stored -- could fall to the floor.
Cost? $10.
2. Already have loose safety straps installed for my lights. One accident already avoided. "Straps" are binder's twine tied with slip-adjustable clove-hitch knots.
Cost? $0
3. Due to possible quakes here, there are issues for stored lenses. My numerous lenses were stored at chest level on a shelf, for ready access. Handy but not good. Although the lenses-in-waiting are in lidded, stiff plastic tubs with cushioning, quake etiquette says they belong on the floor under a strong table.
Cost? $0

A photography adventure story about the Hubble telescope:
http://www.jpl.nasa.gov/news/news.php?feature=2144
Other disasters were avoided before launch. An engineer in Palo Alto built a visual simulation of mechanical movements. The sim showed a critical task to be impossible.
The project manager often whipped out his slide rule when a question came up in a meeting; hed develop an immediate answer, to the chagrin of the computer jockeys.
Hubble out-performed its design the other day, after fifteen years, imaging closer to the Big Bang, as only the unfinished Webb telescope is designed to do. http://jwst.nasa.gov/recentaccomplish.html
