This song works well depending on what you're using the song for. For example, this song won't work as well in the direct meadows or outside, since many of the instruments are not natural. I hate to use this as an example, but Viva La Vida by Coldplay in my opinion has natural environmental sounding pieces. Not suggesting you should build off that song, no, not at all.
Some areas of the song mesh together a lot, and it may sound a little strange. Get the bass cleft less involvement or something, and make sure the sixteenth beats are some nicer instrument. I don't know for sure, actually, I have little music experience and all...Only credentials are criticisms on Newgrounds. XD
The beat is really nice, there just needs to be more instruments and it has to sound nicer overall. I know you probably can't make anything good out of a demo version of FL Studio, but hey, oh well. XD
I wish I can StepMania-tize this...Oh so I wish.
