Short post -
This short IS essentially a comedy, however. So perhaps the feel I was looking to get in the last post was far too serious for that, and some cheerier music would indeed be more appropriate.
I think what needs to be done is to look at the piece, once more fleshed out, and see what fits. It brings up the need to find where on that line between drama and comedy it lies. So we'll see where this turns up in the end.
