Another Ana

I took a few photos of my friend Ana when I sketched her live. Everytime I see the scan of the pencil sketch i did, I cringe - I really think I got so much wrong. She says she loves it and I'm glad of that, but I'm hoping to make a better one, with a better likeness. This was the beginnings of it, but I'm uncertain about the layout. I may have to figure this out more...
