Makke, you get an A+ on originality. I like short and sweet. However, as for the percussion, it's not that everything is in perfect time that's the problem, but that every note is the same volume. A few ghost notes here and there would give this the feel that seems to be missing. If it's a MIDI file, you can easily ramdomize the volumes of the notes, but if it's a wave file you'd have do it manually. All in all, it's a good tune that's fun to listen to. Good choices on the instrumentation.
