Not a bad first attempt at all!
My first attempt back in the day looked like something along the lines of a monkey tripping the fucking shit out on LSD
Anyways, its a simple concept but good considering you actually kept clean dm's, try to utulize grabs into your positioning and maybe even do some fancy shit before you actually start to fuck uke's shit up. Other than that just experiment, make replays, and have some fun and the improvements will just come along the way
