A little too blurry on the membrane. Too heavy with the smudge tool. But good color coordination with the background.

The underside edge of the back of the slice should be shaded.

Fantastic piece author, very realistic and very tasteful...GL

Oooo, I really like the texture of the tangerine slice. It looks so soft and delicate.

Thank you @elinoree, too much soft IMO, I wish more detail but I have't got the skill to do it yet.

Nice image, if you have used a gradient fill on the bgd you may want to replace it as gradient fills are not allowed.

Thank you for telling me that gradient fills are not allowed, I've just fixed it.

Nice subtle tonality really works well to give this dimension. I do feel the edges of the cherry are a bit ragged IMHO, just a little touch up to smooth out the shape is all I'd suggest.
@ibmaxed: Most considerate of you to help out a fellow member with good advice! Polite suggestions like this really help us all.

very nice work author,especially on the main part...IMHO maybe would be more effective with some more dynamic background...GL
