I really liked the lighting on the top of the pears. The way that it plays off the droplets of water is outstanding. I don't like the black shadows under the pears. Possibly a bit more front lighting would have eliminated these areas that look unatural. With better lighting, I would have scored about 2 points higher.
Basically very good - certainly pretty competent; though for this 'buyer' you've over-done the fill light (kills some of the shaping of the pears), and the shadows look forced in processing - kind of unnatural, a bit sudden. The key-light is very effective however, especially on the water drops. Not an image I like very much, but then this is a stock challenge, so i didn't expect to like the good ones really :-)
A very strong photo; good composition, nice texture and lighting. I wish the shadows on the pears did not so quickly fade to black, even understandint that this was done on purpose to remove the surface on which they sat.
This is a neat picture. The black background makes a subjec that may not normally seem that interesting look really cool. And the water drops really add to it! Good luck.
