I shouldn't be making judgement because its rare that I clean a 180, but you kinda do the mountainbike 180. What I mean by that is you don't really use a bunny hop motion, you just kinda sling it 2" off the ground. Thats not really a big deal unless you wanna do them up or over something I suppose. Try lifting your front like your going to bunnyhop then lift your tail as your 30-50 degrees into your rotation. Once again I can't clean 180s most of the time so I feel weird critiquing you, but thats just what I see. Props on getting it.
i still can't clean them really and i'm on a bmx, but part of the reason is i'm trying to break myself of the habit of swinging the bike. it'll look far better and feel far better if you can learn to just bunnyhop and use your hips and head motion to bring the bike around. i'm starting to get it, but it is hard to learn once you've gotten in the habit of carving.
