Trees! Sun! Seed! Walrus!
It was good, the music fit the tone nicely, and you definatly opened the scene up with the crow nicely. I like it. A lot. I got a little bored with it though, specially through the day and night sequences. I apprecaite that you were trying to keep it as "real" as possible, to get the message across in a stronger way, but what good is a message if your viewer gets bored before the end of the movie eh? xD
But no, seriously it's good, and I'd like to see more from you in the future. Keep up the good work, I would just work on more perspective.
