I actually really like this. Seems like you put a lot of effort into it, and there's really nothing bad about it that I can point out besides the fact that there's not much besides that one guitar. You should try an idea I came up with: Perfect Dark Theme/Sonic 3D Blast Diamond Dust Remix. It sounds like a crazy idea, but I'm really wondering what it would sound like now that I've thought it up.
Thanks a lot for the review man!
And nice idea o.o I'll get on it... eventually, I take requests =]
Check out my other stuff if you haven't already ^^ tell me what you think.
Please contact me if you would like to use this in a project. We can discuss the details.
