Kind of plateaus around the middle. Pretty nice sound, but there's not a lot of energy. Just sort of ends up plodding along after a while. That clap sound isn't really helping either; sounds really exposed and dry and outside of the rest of the piece. Around 2:20 things start getting mushy, with a lot of different parts layered over each other. Filtering out is a pretty cheesy ending, especially when it happens so quickly; if you're gonna vamp for an outro, it needs to be longer. The problem is that this song is basically all just vamp, which is not surprising considering that's all the stage select musics really are in Mega Man games.
I think you need more variation in your piece, and you need to pay closer attention to how your elements are balanced. Not a bad start, but needs work. NO
