I'll tell you what I think!
I think that you should be a bit more patient to the posts to come.
Looking at the score and listening as I post.
Generally I like it a lot. I can't say that the performance is towards my taste completely, but the piece is.
It is rather difficult to keep interest in a solo instrument, with no accompaniament, but you pulled it off, so my hat's of to you dear sir!
The score has a very few 'sloppy' mistakes which shouldn't take more than 1-2 minutes to fix. page 3-4, the first system in page 4 could fit in page 3, since it bellongs to the II. lament, and not the rhythm (III). Some dynamics and crescentos clash, but nothing else really. Also you don't indicate where the accel ends, as well as some rit. here and there, which could be a bit confusing to anyone without you on their side.
I comment on the score, which is more objective than commenting on the music, which I did like so...
Thanks for sharing.
