Nice animation overall, but there are some things that bothered me and some that I liked, im going to try to list them:
1. Loved the camera work, nice transitions, and it gave good storytelling with it.
2. the animation bothered me in some details, like the hips, they never move with the running or walk, and the upper body is almost static in the running transition, there should be more movement there.
3. the lighting, GOD it was GOOD!, it helped with the mood, same as the cameras, nice job.
and finally 4. dunno if you modeled all of it (I suppose you did) but that is really good modeling, liked the colors too, really thrilling and gloom like.
Welp that is all of it, a little tip would be to make the animation more lively, don't be afraid to exaggerate the movements and to make more parts in the body move. Can't wait to see more :)
