Re: first one - Agreed that it didn't have a great vibe for me, though it definitely improved with time. camera was far too shakey (maybe consider building a simple dolly to start). I don't really know much about moving pictures, but contrast, saturation, etc. weren't there for me. Could also have had more flow (combination of some bigger/smoother skiing as well as tweaks to editing). The song worked, though I wouldn't have chosen it (purely personal preference). It was pretty good though, and you guys can definitely throw down. I also felt like the end scene, with the elbow, was unnecessary. If you really wanted to show it, I'd have made it much shorter, maybe given it some context (how'd it happen? why is he in a house? was he even skiing when he did it?). Maybe toss it in the middle as well; the whole bails reel, 'what we do is dangerous and we're tough' thing at the end of sports edits/films is sooooooooooo played in my mind. I think it should be more integrated (also gives a better idea of what it's actually like - i.e. you don't stomp endlessly, you ski hard, crash and stomp all together: show that). btw, what did happen?. it looked messed.
Re second one: I liked it a lot better. The can thing aside, the only thing I really noticed was the camera movement on the dock. I would have put the camera on land, set it, and locked up the tripod, started recording, stood back and let him run into the frame. At the beginning I was like "sweet, another lifestyle intro, the athletes alarm goes off, he brushes his teeth, looking super rough, etc.", but I actually thought it was pretty original and enjoyable. Well done.
