As I'm watching it:
The camera walking beside the character- little shakey, the shot coming towards the camera could use a tripod (unless this was the effect you were going for
The russian is a nice touch with the subtitles-has a documentary feel to it.
Good lighting from what I can see-except the shot of him in the apartment. I understand if you were going for the silloutte look, but I couldn't make out much until he walked out.
The shot of the monkey was a VERY smart shot, alluding to previous space flights.
I think a little bit of background music would add to it, but that's a personal thing.
The crossfading between the person and sky works well, as does the "jump cuts' of the home movie footage.
Shot at the 6 min mark-going from the pool to the apartment, maybe a half second too long with the black screen?
Overall, A good looking piece of work, you really got the documentary feel down. Is this the final cut, or still in the editing phase?
