I think, if possible, I would add a little border to the bottom and right to give room for the jump. I would also remove a little from the left border. While the top could use a little space, it is not needed in my view. But the bottom right could use it.
Cool shot here. I like the timing. I agree its a bit tight, but not a biggie. I would try dodging and burning to separate the head from the rocks more.
Unique pose. Looks like someone's been sitting in chocolate chips. I like the detail of the rocks and the focused look he has. That said, I'd like to see where he's thinking on going and more of the habitat (at least lower and to the right) as I like his position in the frame.
Todd,
I have been looking at your image for sometime. I had tried a few alternate crop ideas. Sharing one of those. I would have used a TC. I think showing the vertical cliff gives an impression of the heights and its habitat.
