All of these were shot with my external flash. I think I dialed it down 1 stop for all shots. My camera was set on Aperture at f/5.0 or f/5.6. My focal length ranged from 48mm-50mm. WB set at flash.

Shape/Form

There are a few shadows that give the turkey shape, and the position of the knife and tongs behind the body and in front of the wing lets you know that there is more on the other side. Having my daughter blurred as she watched adds depth as well.

The bright windows in the back are a bit destracting, but also help since the turkey cuts the horizon adding more depth. (On my screen, I can even see the steam rising off the meat.)

Texture/Space/Unity

Similar shaped dishes with different textures in each. The arrangement draws the eye to the back of the image. I may even consider balance for this one. The ladel divides the scene and each side seems to balance with the other.

Proportion/Scale, Repetition/Pattern, Emphasis/Dominance, and Space

Originally, I would say space is the main element and Emphasis/Dominance is the main principle. Then I realized that there are many elements and principles represented in this photo. You can even add color contrast with the splash of reds, yellows, and green.
