Very very nice
I could definitely see this playing in the background of a phone app or a PC program. The song is really relaxing, and yet at the same time there's a distinct rhythm that makes me want to move inside.
Pointers for me:
-If this is going to be playing in the menu or main home screen of the app, then I feel it is ok as is in terms of variance of melodies. However, if this is going to be played constantly throughout the use of the program, then I think that you should vary it a bit more. Currently, you have the smooth piano and the spiccato lead in the background along with the percussion, and it does tend to get a little repetitive after a while. I feel that you could introduce a spacey lead or something in the middle.
-0:31 that transition (or relative lack thereof) is very unfitting. Even if you are going to reintroduce the piano back into the track, there definitely needs to be something to smoothly transition from the relaxing piano to the more upbeat spiccato. Maybe a pause, and a short drumroll or percussion sequence before the other lead starts up again?
That being said, I think the piano and the rest of the track mesh very well. Just a couple things here and there that I think would make this track much better. Good luck to your buddy as well!
