Hrm... need more practice
I'm just going to give constructive critism. That doesn't mean I'm shooting down your work or other thing thats awful, but helping you to improve.
The use of dynamic angle is good. But there is whole lot of things that lacked in my opinion. Despite how cool it looks using extreme angle (the fly through in the beginning was nice I admit), the basic animation was quite poorly done, and with awkward pose. I rather you try study Muybridge for this.
Don't try using extreme angle yet, no matter how cool it looks, if your 'basic' animation movement isn't fluid or good enough, it still look horrible. I've seen better animation than this because they understand how to make it more realistic (the characters movement).
Keep practicing with your design and BASIC characters animation (the one drawn by hand or mouse or tablet, not vector made). I'm sure you will improve alot!
