Well, since we're on the topic... I've been at "this level" of musical composition/talent for a couple years now, and haven't been improving. Almost all of my projects end up like this one - I get a good idea, write something, and it ends up being about 30 seconds of actual "material". And then I get stuck. Usually it goes in the "work" folder and never gets touched again, but sometimes I decide to repeat things and change things to try and get length and variety out of it.
Sorry to just gush out like this, but this isn't, well, the first time I've gotten discouraged with music. I think part of the problem is that I happen to really like very deep, thick chords and part layering, with subtle changes, but I think I'm the only one.
But thanks for the encouragement, guys. You probably still won't ever see WIP #2 of this, but I still appreciate the listens.
