So, I'm working on a digital painting and started out with vector art and then went on doing realistic art, so now I'm thinking about turning this version into a completely realistic one and doing the same one as a complete vector. I've never done vector art realistically though, so some tips and tricks are welcome if you have any. I'm using the Pen-tool in Photoshop. Obviously this painting is not done yet. It's Alexis Bledel, by the way.
