WOW! there's a lot to look at, but I find no rhythm in the photo to establish a solid composition. I look at each vegetable, not the whole photo. Also to note, the photo seems too washed out in the color, almost too yellow (tomatoes, carrots & red pepper especially).
Love how you chose a variety of veggies. The green tones are a little over whelming for me though. The placement of the veggies make an easy smooth flow to the picture.
I like my veggies a little crisper (ouch sorry for that). Actually, I love the colors and placement of all the veggies - but I would have liked the image a little sharper in focus. For example, the edges of the cucumber on the right dont' seem 'sharp' enough. 6
