Wow... brilliant!
Very good. I like the emotion going on here! :) Very strong emotion coming off the melody and sounds. Sounds very sad, yet happy at the same time. I would say it's one of my favorites from you. Especially since it has higher quality sounds in it. Keep making more songs with piano. You'll become a great known person someday if you focus on this. And BTW... check out my new song demo. :) I hope you like it. :D
