1 is awesome. Send it to the printer. I don't usually say that about photos, but that's one that I really like. You pushed the envelope a bit with the subject so close to the edge of the frame, but it works. Logically it works because a man caught in front of a waterfall looking thing would naturally create tension, the placement of the subject only adds to that. There's so much distance to traverse, but so little time (if he were in a position to cross it). This is of course, my opinion.
2 has a nice composition, but the processing doesn't work for me. It is heavy handed, but if toned back could produce a solid image.
Nice captures.
