Okay, here's my thoughts.. I LOVE the artistic nature of the shots as its very different than traditional images. Along those lines, the b/w conversion suits them well. I think you colors look a little off on the color shots and they all seem a bit dark to me. The first image is far and away the best imo as it reflects the activity and uses negative space very well since you have the kite and kit flyer balanced nicely. The darker image actually works well on this image.
