Setting The Tones

I seem to be having trouble sticking to one technique. I've gone from wet watercolor-style renderings for faces to smooth blended painting that seems more mixed media. I seem to be jumping from one style to the other. I need to make sure these paintings have a unified look... so I work and rework and try to get it looking juuust so. But when I used a fibrous brush to get a bleeding watercolor technique, my Mac crashed and I lost all the changes. So I started over. I'm not 100% satisfied with where the face is now, but I do like the shirt, so that's what I'll post here.
