Hey, glad you enjoyed it. Yes, I do pedal a bit at the end and a couple of times at similar points.
I don't have an entire story to fit the whole thing, mainly just pictures that I think of at various points. For instance, at the beginning I generally try to think of someone making a very happy (and loud) announcement. There are parts where I also think of various groups dancing. Generally it's peasants, hehe, although there's one part where I switch to nobles.
When I got the piece to this level I got a bit bored of it, and it lost spontaneity. It was only a bit later that I got a break through and could really feel happy everytime I played it, and as if the ideas were coming naturally instead of thought out carefully and pedantically beforehand. Now I'm waiting for a similar break through in my Schubert but have no idea really how to get it to come. *g*
