Nice work dude!
I'd double what Eatu said about bussing. I'd play around with the piano and the space to make some things near and far.
Composition wise, I think I'd add in some upper register development, maybe some vocals. I remember just hearing the word development helped me realize that I hadn't been thinking about it to the degree that I could in my music.
Regardless, you did a great job, I liked the nostalgic sound of it, great work! :)
