So I'm watching your Sin matches and you're doing great. You're keeping the pressure and I noticed at least one occasion where you burned meter to prevent him from having a safe way of eating food. Good job on that. Some things that I saw:
@2:34 - You landed a dust in the corner and got the wall-splat but seemed like you weren't really ready for it and it resulted in no extra damage and losing the corner. That's just a composure thing.
@3:31 - You're down to pixels and have bar to make one combo win you the round, so when he whiffs his super you had time to do most anything you want. The game is still crazy young and I haven't seen anyone work on this kind of thing but that's a situation where I'd want a developed burst-bait setup in my back pocket. So something to thing about if you (or anyone else, share the tech) are ever in the lab.
@6:49 - I noticed this round that you've gotten him into the habit of mashing and it looks like you noticed it too because you did a very nice dandy punish of his wakeup. Slayer really wins when he starts conditioning his opponent so now I'm guessing you're going to start punishing his mashing. Then he'll be afraid to push buttons and you've already won. Well played sir, Slayer would be proud.
I'll leave that, I'm waiting for more work to come in so nit-picking your play is apparently how I'm filling my day. Sorry to seem to go on a bit.
