The modeling is good, only crit on that is the red apple is a bit diamond shaped, should really be either round or heart shaped.

The actual textures are good, though they need to be a higher resolution, right now the details look a bit blurred. The materials at this point seem like lambert, the grapes could use some translucency and as others have said, some specular maps would do wonders, that orange needs to look juicy! :p

The lighting, good start but its flat and there are no contact shadows.

Keep truckin'.
