The flower shot is my favorite, but it's a little underexposed to me. I think the chess piece shots have some potential, especially numbers 2 and 3. The pieces aren't straight in number 2 (leaning to the left) and their bottoms are cut off in number 3.
I think I'd be more interested in them if the pieces themselves were more interesting. As it is, they're just cheap plastic and, as others mentioned above, the untrimmed bits are distracting. I think if they had a more interesting texture (maybe stone or wood) to contrast more with the soft background flower it might work out better.
