Fast Metal without vocals

I only use 9 tracks in a recording without vocals, 3 guitar, 1 bass, and drums, the drums are programmed with EZ drummer. I’m a guitarist with a passion for Metal and get a paid vocalist to sing and write my song, just for fun. I am learning the art of mixing, but want to hear what other guys/girl can do to my tracks :) I will give a link to my track in next post. The track is in 220 bpm
It feels like there's no way to download tracks from Soundcloud... but then how we gonna work that out? ))
Maybe googledisk or smth like that?
