I like the beat, I'm going to throw that out their right now. Although the guitar is obviously fake, its kept under the weather enough for me not to point fingers at it (although it'd be sweet if you got someone to actually play some real guit-fiddle there).
The mixing is, at the moment, questionable. The drums sound like they've got too much flanger and are playing from inside a full bottle of water.
This is a great theme to mix (even after hearing it a million zillion @!#%$!!! times), but at the same time it's popular, meaning people won't want to be disappointed. Good luck on future touch ups, as of right now I'd like to hear what results with more work added on.
