Not bad man....

Try to record the rythm twice, one panned left and one right, or use the same track onto a new layer and just delay a few millisecs, just to give it a bigger stereo sound, if u know what I mean...

Also turn up the lead guitar level it did seem a bit too soft. Actually the whole track sounded a bit soft, maybe u could turn up the tracks level and in ur master track put in a limiter so it doesnt clip... if u know what i mean....

but nice idea u got there man :)
