Sorry for the long hiatus, been doing a lot of brush and stylus experimentation in mangastudio 5 and on the new tablet that really isn't just post-worthy. It really offers a lot for the price point and with plenty of features that I don't have with PSE: a more complete interface, pressure curve adjustment, it's own built-in stabilization. But at the end of the day, photoshop with lazy nezumi just feels right. If I do need more features, I'll probably take a look at photoshop CC.
Here are just some basic head and gesture sketches plus playing with eye coloring when I jumped back to pse. The harder brush produces a very gem-y look that might be a bit too showy. All in all, a good look though.
