Ok, Running openers are ok imo, but tbh you took a while to start running.
After getting closer to uke the weird stuff starts...you make ALOT of useless hits, just making some damage, without putting something on the replay
The CoreKick were pretty cool imo, but just make uke get higher to make it looks stronger.
one thing i would say you to do is to attemp making stunning stuff> when uke's body was falling, you could easily do an transition to make a better kick(an air kick,an spin kick etc) than the one you actually made.
you don't seems to have issues with smoothness on your movements, but i'd say to work more on transitions and hits. Other than that its a pretty cool replay
