A. The lighting level looks reasonably OK for an indoor scene.

B. Not nearly enough contrast.

C. Too much contrast. The Black Point looks a little too far down, the White Point looks about right for indoors, a bit low for bright sun. C looks a lot better than B.

D. Reasonable, could use just a smidgen more contrast. I could not pick any major fault with this image. The saturation looks quite high (boiled crab), but I assume that is intentional.

E. Not enough contrast. Needs a bit more red and blue.

F. Not enough contrast.

G. Too much contrast. Too much saturation.
