Need opinion about my (future) Megawad MIDI.

[Rorque.]

Hello there. I'll get right to the point, I'm preparing a megawad and I've started to write some music in MIDI format. So, I was wondering if that was good or not. That's why I need you to have some advices for the next music to come in the next time. 

Thanks ! ;)

P.S : If the first ones sound poor (level 0 to 3), that's normal. It's showing (IMO of course) the player is gaining strenght by crossing the levels.
