I like the idea here, very original. The only two nitpicks I have is the background being a little darker on the right than on the left and the cut surface of the lemon seems a tad blown out. I know both are hard to fix with limited editing allowed. Having said that, I really do like the shot. Nice work.
It's hard for me to be objective about this photo because of the clash of the unmatching yellows. The focus and lighting are great, tho, and I do like your composition. So, I'm trying to get over the unnatural color of the hand :)
if thats what u think of when i say yellow than great.
but i feel that this shot has no artistic value, and tech. you should've let the paint dry then it wouldn't have been so runny and would have a sclptures texture.
