RA: Analyzing a picture

So I have a lot of art that I like, but it seems that just because it's a picture doesn't mean it has a WATCO. I was going to do the photograph that's from the Great Depression...the one with the mom and her two kids? However, I thought I'd do a picture you haven't seen before and it's really really gorgeous. Go here if you want to see a larger version. It's an artist's rendition of Vanity, one of the seven deadly sins.

WATCO of someone who is excessively prideful on their perception of the world?
Enthymeme: Someone who is excessively prideful will distort their perception of the world because someone who is excessively prideful will only notice the parts of the world that pertain to themselves and ignore the rest.
Implicit Assumption: Anything that causes people to notice the parts of the world that pertain to themselves and ignore the rest will distort their perception of the world.
Intended Audience: People who like contemplating gorgeous artwork. (It sounds bad, but it's true!) Also for other artists who would notice the small symbols she uses in her drawings.
Ethos: I think her ability as an artist lends to her ethos
Pathos: The color purple, which is often associated with vanity, is the primary color of the picture.
Logos: The peacock tail pattern, the mirror, and the desolate landscape in the background are all familiar symbols that have been associated with vanity before, so it makes for a good argument? Or this might need to be in ethos...
