Beauty is...

I've been working on my watercolor final in which we have to respond to the statement "beauty is".
I went through a couple of thought processes starting with things like beauty is growth, beauty is ephemeral, beauty is changing...and somehow I ended up with something that doesn't really have as clear a thought process as i was planning.
So here is the initial sketch idea and color study. These are only about 9x12, but the final will be 18x24.
