great work man, I liked the concept a lot,are you the one who draw it ??
for the 3d model, it looks so nice and smooth, maybe need textures and materials like the one on the concept
also, I was hopping for a larger image, and a wire shot too ... that may make it more clear to judge
I read on vimeo that you didn't finish the compositing of the animation yet, but am a bit curious about the environment on the animation
is it a real video? camera mapping? .... or what ??
anyway keep going, you are doing good ^^
