Ugh... Sorry. The random stops and skips bugged me way too much to even go father than 30 seconds into the real hitting. Your footwork on the run/move seems suspect and your ability to handle low balls seems to be rather weak (as a result). That's just from a glance. I could be wrong.
I'd guess 4.0 overall. Not bad. Put up a better video and I'll give you a better response.
