You've certainly met the challenge with all the variations of green that you have in this photograph. Obviously you took a lot of time setting this up. I like the draping of the cloth as a background. It doesn't overpower the subject and provides a nice neutral color to allow the other colors to be the main subject.
From a composition standpoint, I see two main areas or groupings in this picture - one on top and one on the bottom. In my mind, they tend to pull against each other. I think that you would do better with fewer "subjects" and to provide a single grouping which is the obvious "center of attention". Then place that "center of attention" in the frame based upon the "rule of thirds".
Technically, you've done pretty good but I do see some "noise" or graininess in the cloth background which is distracting. Lighting is a little too strong mainly to the left of the photo where the bowl is slightly too bright. I personally would rather see more shadow than have an area too bright. Focus is pretty good but I see that this was taken at f/5.6. You would probably get even better overall focus by taking this at f/16 and an even slower shutter speed (naturally, on a tripod).
there seems to be a haze over this whole picture. Maybe playing a bit with the levels will boost the brightness and contrast and get ride of that whitish cast?
Seems slightly lacking in colour - almost a grey caste to it. Good selection of objects for this still life but I think it needed a slightly tighter arrangement. 5 - floyd
Too much stuff!!! Actually I like the foreground things, the item and it's other half. How about forgetting the salad bowl part and working with those shapes? I love the colors here and the cloth is a nice compliment in color annt testure. the wood is wonderful. Simplify it.
