I can't give any constructive criticism on that, it's rather beautiful. Although, one note on it as I've just heard the end... you could do with working on an outro for it as it ends quite abruptly, it's the kind of song you could give a really soulful outro. For example you could have a smooth decline in tempo paired with an arpeggio and a nice bend to say goodbye, y'know, something like that.

P.S. if you're interested in doing c4c I posted a thread titled "EDM/guitar track" a few mins ago.
I was finished and needed to move on. As the saying goes... always leave them wanting more. P.T. Barnam
