Nice layers and meshing with the piano and the strings. it's a simple tune but very well done.
I like the energy in the piano, definitely. The song has a good feel to it, sounds like it's building to something really big in the end.
You could add a bit more harmony to your strings, maybe put down a beat behind it. The piano is strong in itself, and it does carry the piece - but I wish I could hear more.
Ends abruptly - but I actually like it that way!
Rated 5, definitely.
