Great perspective on the challenge theme! I like the angle of compostion. Colour looks very natural too.

VERY clever idea! =) The focus looks slightly soft, but I really love the angle.

I never knew his middle name. I like the angle. Did you know that it is best to take pictures looking up at adults and looking down at children. It is supposed to be more natural. I hope Kevin doesn't take this bad, but his hair (stubble I mean) looks a tad green. I am guessing it is a color cast from the plant (or something else green) behind him. If that were the case having a different background could easily fix that. I also think it would be a little better if the top of the head were not cut off.

Interesting take on the theme. I have to add to what Janae said, looking up at somebody makes it feel like they are more important, so I think this was a good choice of angle. I also really love that there are reflections in his glasses. Nice use of the rule of thirds on his eyes as well. I think this shot just missed nailing the focus. Try to make sure you focus right on those eyes. In a portrait the eyes are the most important, if they aren't tack sharp the rest of the picture looks oof, even if its not. Nicely done.

Great, creative take on the theme. I also like the reflection in his glasses. Good shot.

Interesting take on the theme. Like the angle and composition of this shot.
