Your Story (Piano Concerto)

This was my first attempt at writing a concerto, so any tips or feed back is greatly appreciated!

As a first attempt, great. Is it meant to be part of a 3- or 4-movement piece? It doesn't seem to make particular demands on the soloist. The harmony doesn't vary enough for me. It seems to shift between the tonic and supertonic with  no cadence. I'd have liked it to move on to a second contrasting subject at around 1'15" - but that's a matter of style. If you're happy with just one theme, fine. The shift to a slightly different tonal centre at 3'15" was welcome but basically it does cry out for modulation and development. I liked the simple accompaniment that does contrast well with the piano.

I'm with Quinn. After I listened the first time, I dragged the slider into various points of the piece and always heard a tonicized E-flat somewhere in the bass or melody. The orchestration is needlessly sparse, especially for some of the bigger moments.
