The first one you seemed of you off, most of the movements were hurried. I didn't see the clean movements/lines that I normally see. One hand would move somewhere else and break the illusion. Although you seemed off it was still a great clip.
Second clip absolutely blew me away. The little upper-body push and pulls were well executed. I could go on an on, can I list the whole video as my favorite part? I will say this, once or twice I saw the same issue as the first. I will have to give times and examples later.
