I really like some of your ideas.. Particularly the descending figures in bar 49, after the trill. However, I have to agree with Gamma that it overall feels a tad incoherent.. Particularly after that passage I mentioned, I think after your fermatta it goes into the softer theme a bit too abruptly. I do like that theme, particularly how you go from F to B to A flat, I think it's a very nice sound.. It's also funny how you put exclamation marks after your sforzandos at the end! I do like it, it sort of sounds to me as what it would sound like if Ives tried to evoke what you explained or something :P.. Good stuff!
