I found the snare on the intro distracting. IMHO I would not use it. Also the intro should be cut in half. I do like the snare in the break with the electric guitar, it blends well. I would also cut the song down to two minutes, it gets a bit repetitious without melody lines or vocals. You could also lengthen the bridge part X2, it was interesting and could be told again.
Instrumentals can be short, 1 to 2 minutes. Say what needs saying and end it.
