Neat-o ^.^
Great mix of instruments and a great idea!
Only point is that I think it would be better to change the lower piano melody that comes in at 37 seconds to synth. I think it would mix quite well with the rest of it, but dont do it just cause i said to >.< It just what I would prefer, i like stuff like that.
Apart from that youve made a good little peice of artist music ^.^
Keep up the good work!
