You have a decent setup for a song here, but it does kind of drone on for too long without any real change. That's fine if you are specifically going for a droney style, but a successful drone piece tends to blend into the background and not remind you that it's looping. The minute at the end feels really out of place, and it doesn't really connect to the first song at all, not to mention that it literally just sounds like someone mashing keys randomly.

Keep working on your craft, but I would suggest leaving tracks like these off of Newgrounds. They're better left as reference points or experiments.
