Tis sounds quite nice, but can you play it on the guitar? it sometimes seems too fast. Also try adding a solo
with the chugging parts- try chugging only the one note on the D string.

also try harmonizing....

i do like it alot though. pretty good if you can really play this.
It was alright... haha not much else to say about it. As for what to do next... I dunno do a pickslide and do a heavy chord riff... In a different timing or key, or it would get boring.
