Get some stereo in there! Everything sounds pretty mono and dull. Try to EQ things to make those sounds more interesting ( there's no bass nor hi in there, only mids ), and try to make the whole thing stick together more, instead of just separate samples played in a certain order. It's not like your ideas are bad, it's just they're not worked out enough i think. But hey, that's just my opinion of course, nobody forces you to listen to it :)
