This is looking very good, the apple especially. The other fruit could use some work though. I looked for some good reference images (using google’s image search tool) to help you out:
The light reflecting off the orange seems a bit too extreme. Tone that down a bit. Otherwise, the orange seems pretty good, as long as we assume that both oranges seem to have hidden their navels from us. I think it would make more sense that we are able to see the ends of at least one of the oranges.
The bananas are far too singular in color. Look at the reference images to see what I mean (particularly the first. Also, the stem and the end both seem to be more balls then they are proper ends. If you look at the first banana reference picture, you’ll notice that the ends are anything but round. Maybe you could use a more sharp displacement texture on the black parts. The shape of the bananas seem a bit wrong too; I’m not good at describing this though, so observe the reference picture. Oh, also… bananas aren’t round, really. They have parts that can easily be peeled away. Look at the first and second images to notice how that works. You might want to use the loop cut tool to get that effect. Finally, if you want really good detail, you should add a minute bumpmap of line textures that run up and down the banana. But I don’t think that’s absolutely necessary.
As for the grapes… the new texture you added is good, but they look like plastic. I’m not sure of the best way to fix this… but I sugest observing the reference images.
Finally, tweak that table! The grain in it looks disturbingly perfect. If you are going to use straight lines like that, you should have multiple “planks” of wood in the construction of that table, I think.
