Hm... You have the Anime concept down spot on, very little actual animation but quite well directed. However, the inconsistencies seem to me to be a little too distracting, most importantly how in some scenes Sonic has pupils and in others he doesn't. Also, at one point Sonic looks angry, terrified and then angry again... I think maybe that the "scared" one was meant to be Shadow. All in all I think if you keep working on it you'll end up with a rather cool video as the direction to me showed that you have the eye for developing a dramatic atmosphere.
