Unrusting uno: Love the bounciness of it, the reactions are really stiff compared to how you animated the main stick. Just watch that.
Unrusting two: Pretty cool the movements were solid, love the lead up into the first uppercut, the stutter step? If that's what it is called. The only thing is the kick before the wall look really weird, like a quick boner attack ;)
Unrusting Three: Not much to say just a short little thing, looks good to me.
FOUR: I think this is the best out of the three, the moves themselves flow really well together and they're creative, really good anticipation too.
Overall keep up the good work, looking forward to something longer or a short anim.
