No bad, kiddo.
Your madman/singleplayer replays are alright-ish. I have similar SP replays. Its OK, not all of us are noweb or chez...
Multiplayer tho is rather pedantic stuff. The first MP replay is a "luck" win for you. You got decapped, and the other guy just plain failed. Not really any skill or anything.
The second is a simple arial momentum shift. They are fun, yes, but rather standard. I'm sure you'll find yourself doing that more times (and with more destructive results) down the road.
Keep on truckin' man. I'm expecting better replays from you next time. Don't let me down.
