Overall, you have a good understanding of movement, but you need to work on your flow and smoothness.
Keep a constant speed, try not to change any joints that you changed only a few frames before. (Ex : left rotating chest then right rotating only 10 frames after)
If you change your joints real suddenly, you'll look twitchy and it'll ruin the look of the replay.
On your skeets, always make sure you can get the throw on the first try. If it doesn't work the first time, watch the replay again and edit where you're about to throw to adjust it more. It looks really messy when you contract and extend repeatedly.
About your hits, they're solid. But, you pull Uke in too close towards you, making it hard to make a nice, clean hit on him. Try to make contact only with your feet or hands, and make sure you gain a lot of speed to get a really good contact on 'em.
In some of your hits, I see a lot of potential to make it into a boom. Try to spend more time aiming your hits, getting your arms or legs in the right position to rip through Uke.
I'm sort of blank on what to say right now, sadly.
But, most importantly, if you don't make something exactly how you want it, just go back into the replay and edit it over and over.
Another important note, shift+space will really help you with your aim and control with pretty much everything.
Good luck, keep practicing and learning. You have potential.
