Cool song! My suggestions to improve it: you could add a little more background noise, just little things here and there to make it more interesting. Maybe add a stronger bass, although I can't be sure that's what's missing because my headphones don't do bass well! And from 1:52--2:08 you might want to push that violin thingy to the background a little bit more so it doesn't conflict with the piano melody. Unless you want the violin thing to be the melody, in which case move the piano back. Anyway good job!
