It's not bad at all, way better than ech (the prototype) for certain. But as this is a review, I'm of course going to try to put in a couple suggestions. Nothing stands out to me about the notey stuff, or should I say the stuff that isn't the drums, it's good enough that no suggestions come to mind immediately. on the drums however I have a couple of thoughts.
Or maybe it's just one thought.
The shortest hit on the drums (the one that goes one two one two) doesn't feel like it has enough energy to it. It feels as though it's standing still, rather than sending it's feelings along the path of the music. If that makes any sense.
Only a little though, since after listening really closely I it might be fine the way it is, you did quite well. It's hard to come up with anything to pick on.
So instead of trying really hard to find something i'll just give a little suggestion to try out in future pieces, and that's tiny sounds. One of my favorite things about music is closing my eyes and being able to listen to exactly where each sound is coming from, and I love when tiny (not necessarily quiet) sounds are sitting way far out to the left or right.
I enjoyed how the lowest hit on the drums moved around a bit, the wiggle from left to right that the ending sound seemed to have. The cymbal up in the top right corner was interesting too, and it was nice how the background synth spanned the whole space from left to right. The other three far corners didn't have anything in them, but it wasn't a problem at all.
Gah there are so many parts of music, I don't even know how to begin on the choice of melody, as I don't really think about that specifically very often anyway.
One thing's for sure though, you did a good job for such a short piece.
