Short Unfinished Piano Piece in E Minor

Short piece that I composed but haven't had the muse to complete it. Wondering what you all thought of it. Thanks! 

This is beautiful. There is great passion in even a fairly simple piece. The strings give a perfect added depth and around 1 minute where you have the melody over the top of the piano (sounds like a horn but I'm not sure) is very good.

I feel like the ending is a bit prolonged compared to the rest of the piece. Maybe more development before that will help?

End of the second phrase where the piano tremolos I would suggest forgoing the tremolo (sounds unexpected and space-fill-y) and have the strings play something over it instead.
The quintal stuff at the end was really cool, but never felt super satisfying as the piece ended. Since you transformed into the inversion of it, it left the counterpoint a little bare without much resolution to the previous section.
