Looks good!
A tip for future units: if a character moves his feet, his pelvis and upper body should move as well so it looks like he is putting weight on his feet. Otherwise it can seem like his upper body is just floating and he's waving his legs around like tentacles. Also, I think at this scale it's better to over-emphasise, rather than under-emphasise, upper body movements during attacks. Then it looks more natural and flowing, and less stiff. Although I suppose a copper should be stiff if anyone should.
