I liked it, very nice idea to start with

; I think it is worth to work on it. It feels very much like the beginning of a movie to me, like the intro for a university related kind of movie.
I think that the lowest note in the piano sounds too high, I mean, it has too much volume, I would like it to be about half the way from where it is now.
When the strings arrangement comes to life, I would like some radical changes in the harmony, but still under the same tempo in the piano, because this is the very reason of the mood of the song. And would make some violins sing long notes over it, rather than staccato.
Then I would come back to the first part of the song, without changing its harmony, and would put on top of it a oboe as the first melody (which you should still create over it) with rather longer notes too, and I would add a fagot to make some arpeggios in counterpoint with the piano, that would make a really cute tune.
Well, it is just an idea of what I would do, cheers.
