VERY GOOD.
Tight work.
From the looks of your artwork and the animation in your trailer,
I'm guessing you're an animation student,maybe? Anyway, loved the character designs, the overall art style. Are you going have the characters voiced? The music was okay, I thought you could have picked a better piece, and in that animation at the beginning, you also should've had his scarf move with the wind. But otherwise, no real complaints here.
P.S : How long did it take you to put this together?
