Ahh same thing with this one...just more messy...take your 'x' coefficient (-3) and divide it by 2...then square the result...and you get...?

anonymous · Answer

primeralph · Answer

I don't get photography. It's cool, but I just don't see what's special about it. Guess I need some inspiration from insagram.

anonymous · Answer

Haha, well I like to take pictures of nature then paint it, so I guess im in it for the art (: @primeralph

primeralph · Answer

That's awesome. I don't know how people stare at trees and grass and decide to draw it. Seems hard.
Can you show me somethings you've done?

anonymous · Answer
