Been a while! Wow, the interface has changed in the past couple years!
Anyway, here's a portrait I'm working on.
I'm not so worried about things like the pose, anatomy, proportions, and such. Those things will get better with my daily practice. But if you do notice any small issues like hands or face, feel free to point them out. It's still rough enough for me to make plenty of changes.
It's the lighting/colors that always seem to give me trouble. No matter what approach I use, they never seem to feel right. For this one, I started with a dark color (the deep purple) and started painting the colors over it as both laying down the color, and adding lighting.
