What would have really taken this photo over the top would have been some moisture droplets and perhaps a brush of sugar along the edges. Still, very nice and appetizing looking.
I think sharper focus is needed on this shot to really make it stand out. Also, I think you could have gotten away with a little more colour saturation. JMO
Focus is slightly off, otherwise nice photo, although I'm not sure the sliced strawberry added to this image...more red & green would be better, I think.
4 - Colors seem to have come through 'true'. Focus seems off and/or a little 'blurry'. Traces of grain/something as well, which could be due to resizing, who knows. Like the crop. Just like to have seen the colors tweaked more and (although looks difficult with the 'white' of the cut strawberry), as mentioned, more detail and texture. Again, quality dependent, this at 640 would have had more impact as well.
Mmmmm strawberries. Cream... must... resist.... mmmm.....
Maybe this would work better with ripe strawberries which are of a more intense red. Also the light (flash?) reflection is a bit distracting.
