Half-themed, no coherant support
Your main melody and the drums later are this tune's best character.
Before that there's a bit too much dissonance and it's really difficult to "find" the feeling of the tune.
After that the track sort of 'coalesces' into something listenable, but breaking this tune into main areas, variations, and bridges might do it well.
This one's pretty far from being what it could be in terms of pure kickass, but the ideas are presented are admirable... just too ad-hoc.
