Nice! These drums sound really evil. I think it would be nice if there was a little more articulation a few moments where the song slows down and speeds up in between sections or an entire section part of the song played slower and softer to get more variation. The three hits at the end could've been louder. Increasing in loudness, to make it more clear the song ends. Even though it's only percussion it sounds interesting enough as it is, because the instruments sound so varied. It would also sound good with other instruments over it. Works well as a demo. I'll be sure to check storm drums out.
