well....
The intro wasn't very well thought out. See, if you study Beethoven you'll realize that Beethoven loves introductions to his pieces. However, moonlight sonata does not have one and that is unique for Beethoven. So adding one I thought was a bad idea.
When you got to the real music part, it was way to slow, and the chords weren't exactly right.
Using the material you did for the ending really killed it, made it to strident and choppy when it should be dark and fading away.
Keep trying tho.
