i realise that i am probably very late in giving u advice, but I will anyway:
The melody is very nice. It reminds me of Chopin, but ill leave it at that, because I dont like been told myself that my piece sounds like someone else. So, this sounds like you
I do feel like this is a potential nocturne, so thats good...and obviously a midi doesnt do it justice. I think you need to work the harmony out a little more in the main theme. It just sounds naked...and unfull...even if you make it more 'fuller' on the later repetition of it...that should be fine. Its the second chord i dont like too much...i can hear in my mind a leading note that could be chucked in the left hand chord (the Dsharp...or even an A major chord...I dont know because i am not in front of a piano, and dont have a score...but yea...the second chord doesnt sit will with me.)
other than that, if you have finished it since u posted it 5 months ago (lawl)...thats great...but if you have dropped it...pick it up again and go with it. YOu might find some new inspiration.
