The ending was actually written that way on purpose. I wanted to write something a bit unexpected, something that you normally would hear in music from the classical period or in romantic music. The whole piece started out as kind of a experiment where I wanted to combine those styles with a "modern" tonality, but I'm not shure if that is what I ended up with. That is also why I use a theme by R. Strauss in the mid section. I see what you mean, I also find the ending a little out of place, but I'm not shure if I want to change it or not. Any suggestions?
About making a pdf of the score, I dont have any programs to do that with, and I don't have the administration rights needed to download one, since the computer I wrote the score on is locked to my school. I'll talk to my teacher and ask if he can help me!
