Ok, I don't think I did too great with this one. It started out good, went to better-but-there-is-something-missing and finished as I-hate-it-now.
It happens. The important thing is to leave it and do something else. It might look better in a few days... or you might get an idea how to fix it.
("fixing it" can mean tearing the page, too)
Don't be too precious about your art. It's just paint on paper.
Take care and be well!
