This is definitely a colorful shot, and the fruit and vegetables look very fresh and appealing despite the comment about the olives. I love the colors produced by the wide variety of delicious looking produce.
I think the f3.8 hurt the depth of field a little making the layout not as sharp overall with this close shot as my taste would prefer.
I do have some issues with the fish. The glaze on the eye and the shininess of the skin make it appear to be not as fresh as the rest of the food. You may have been able to correct that with a polarizing filter and some lighting corrections. I know you can't keep fish long without them getting that glazed look in the eyes.
Personally I would have preferred the fish not being so tight in the corner, especially its face, and having some vegetables around the top-left part of the picture.
I do like the clumped layout of the vegetables which looks more realistic than if it was all tossed together and laid out more randomly.
The subtle frame works well here. I haven't used frames myself, but I do like them when well done. Good job, and I'll come to your house for dinner anytime!
