good...buuut
I loved the animation, good theme, however the motions were to cut and dry the movements didnt really seem human rather just point to point. just a personal opinion but I feel it would be a lot better if you made them show a bit more restraint, confliction, stop and release, a good book to read on human motion is *Eadweard Muybridge - The Human Figure in Motion* it is a really good book, pick it up if you can or just download the e-book. It has helped a few people with the same "problem" you have.
i quote because it's just a opinion and not really a problem I guess.
anyways though, it looks really good. If you choose to pick up and read the book or download it which ever is personal pref then I am looking forward to your next work. good job
