Everything was incredibly smooth and clean, you get a 9.5/10 from me, in all of them. Sorry for no C&C, but those replays have to be watched in detail to be constructively criticised.
EDIT: Thinking again, I'll watch them on detail.
Bullet Bill.rpl: Everything was pretty smoothened up, until you reached the end, where you slowed down a bit. The replay is overall slow, and I'm not a big fan of slow madmen. Still, it's a 9/10 from me, because it's overall smooth and good looking.
Platypus.rpl: The best replay of the 3, in my opinion. It's just a madman, no way around it. 10/10
Saltines.rpl: I loved the decap on it, because I'm a huge punch fan. In fact, I didn't notice you DMed the leg later, so you get extra points for persistence. Overall smooth and nice, not much to say about it. 9.75/10
