Gotta say, that's one of the trippiest metal songs I've ever heard.
The loud parts sound good. No critiques there (but then I probably don't know what to listen for...)
During that quick break in the middle where it's just the one guitar playing a short lick, I'd pan that guitar more towards the middle so there's at least something going on in the left side.
You've got a fair amount of dead space at the end that you could probably stand to trim off.
I wish I could tell you where the cream filling is, but I honestly have no idea.
