The song is well put together, but the mastering could use a little work. You have so much noise on the high end that it is distorting the crash just about every time you nail it. And you just about lose all bass at the 0'27" mark. That's the only criticism I can offer, but it seems to overpower the whole piece.
I should have mentioned i made this all on PXTone Collage. no mastering options there. though i could've mastered the mp3 on Reaper then posted. oh well. thank you for the review! will keep that in mind next time.
