Different for sure.. IT has a happy tone but at the same time a sad one also. Its rather strange to listen to.. I'm hearing some vocals in here (ohh's and ahh's) wich work well in the song. I'd say over all you've done a pretty darn good job here! Keep it up!
Feel free to add vocals, I'd love to here it as it's a very good idea. Let me know if you do.
Cheers for listening and for your suggestions,
