I like it. The ticking isn't exactly clean, like 'stop' and 'go,' but I actually think 'fast' and 'slow' has a lot of potential here, once you've got it under control. If you're aiming to do 'stop' and 'go' ticking, maybe it would help to think of it as you're standing still, but movements keep bursting through you, rather than you're moving and trying to stop intermittently. Or if you're already doing that, maybe vice versa? I don't know, I'm not good at ticking so take that with a grain of salt. I think you should ditch the hand around the face thing, though. That's feels a little cliche.
I found the short sleeves distracting. I'm one that tries pretty hard to avoid making clothing an issue in flow; you should be able to do liquid no matter what you're wearing, right? Like, Batman wasn't a real superhero, he just had a suit. We don't want to be Batman, we want to be Magneto or some shit. Sad to say, the elbows were too sharp much for me. Maybe find ways to 'cheat' with your flow, or just wear long sleeves.
Good work otherwise, I enjoyed the clip. :)
