Hi Kris,
I have to say #3 is my favourite. The colours look very natural and crisp. Looking at the photo makes me want to reach in and grab one of those apples and eat it!

Photo #1 is oversaturated for my liking (especially the grapefruit), but that is only my personal preference. #2 seems to have a bit of a greenish cast to it (looking at the mandarin oranges and kiwi fruit), but that could be my eyes deceiving me by making up for the strong yellow and red hues in the other two pictures. Nice job, but now I'm hungry..
