Awesome work. Looks very authentic.Only the juice drops are missing.. Good job here.

Nice job. A few quick suggestions though.

1) The kiwis look a bit dry. If you have spec on them, it should be increased to make them glossier and give some nice highlights that will sell it as being juicy.

2) The kiwi slice that is resting on the other looks very stiff. Adding a slight bend in the middle would help enhance the realism of this shot.

3) The kiwis don't seem to be casting any sort of shadows. The top slice should be casting a shadow or at the very least there should be some occlusion between it and the bottom slice to help ground it.

Again, very good work! These critiques are only meant as food for thought so I hope you don't take it the wrong way.

Not at all, Im just glad you're trying to help. I tried adding shadows and better reflections but with the blur, the rendering time was just too long.

hmmmmmm, not bad
