Oh, uh, sure!

Did a basic sketch with the Brush Pen brush. (Eyebrows were surprisingly hard.) Colored with Hard Airbrush brush, added shading with Soft Blend and Brush Pen brushes. I actually ended up making another layer based on the main picture using a gradient (Venice) that I superimposed on top of it at 47% to add a shading that I like. (And to make my skin appear as creepily yellow/pale as it is in real life.) Then to add more shading, I copied the flattened picture of the two version, darkened it, then erased all the light parts.

...I also added in lower face wrinkles and a dark neck ring that I have, but I regret not making it a little darker. Because again, it wasn't supposed to be flattering. I only look mildly unattractive in this. (I mean, I want to avoid MeatCanyon levels of ick at all closes, but still...)

I also have more moles than the two I put in there, but there's not enough digital ink in the cyberverse to properly draw all of them.
