ehhh definitely too stiff in everything above the neck, and the shoulder/cleavage area is really messy. I would recommend fixing those areas and improving your AA. Not trying to be negative, but the title has 'practice', and you need criticism to know what to improve :p
This is one of the best walk cycle I have seen on this site! The only thing that bothers me a bit is how her shoulder is a bit jumpy. Maybe improve upon that in an update?
The animation looks perfect! (it just lacks a bit of movement in her hair i guess...)
Love the movement in the arms and legs and how the skirt swings!
The shading in her face looks a bit weird though...
Anyways, It's really good!
To me the body really looks 3D, nice job!
