Sorry it's been so long, guys. Here's a handful of recent sketches I've been working on. They've all been colored over in gouache. I love that stuff. It really gets me leaning towards color application.
The first batch of gouache sketches were all based around finding a final design on my female devil character (the one seen a few posts down). She wasn't doing so bad here, but I kept falling into the large head category, which bothered the hell out of me. She was looking way too young. I was diggin' the color sceme in the lower right drawing, though.
After pushing aside another grotesquely large head in the top left, I started pegging her proportions down a bit better. I added glasses to give her more of a mature work area look, and eventually really pegged it down with the bottom middle sketch.
