I find the background a little distracting. Perhaps the lighting could be a bit brighter on the foreground subject? Also I think you could have made more use of the knife as a strong linear element, and perhaps a less centered composition. Nice colours in the peppers though.
Wow, I see many errors here. Focus is where? Nowhere. There are two different light sources, window and a bulb from above, not looking good. And the stronger light source (window) is behind the subject. And backgroud is filled with objects distracting attention.
