Good song, with a bit room for improvment
The song itself is very good. I like the instruments and I like the style. It would have been nice if you have repeated the theme as ending once more without distortion. One note only is not enough for me ;-).
Technical you can do some things. The overall sound is a bit dull. There are simply not enough high frequencies. You could try to put a lowcut filter on your e-guitars between 100-200Hz to "tidy up" low frequencies. In my opinion the drums could also be a litte bit louder.
All in all a very nice song indeed ;-)
