Hi, Ben:

If you're only 14 and have that much music to your credit then stand up and take a bow!

I like the beginnings of your concerto. Very nice mix of modern feel and "serious" music intent. I'll listen to the others over the course of the day.

As a bit of a pointer from someone who's had some "real life" orchestration experience, your flautist won't thank you for writing in C#. They tend to get cranky anywhere for 4 sharps or flats. The strings don't really care; they just slide their fingers up and down anyway.

Did you mean to go to four sharps at bar 26 or is that just an artifact?

Keep composing!

David
