Alright, the holidays provide a brief distraction, but let's keep the ball rollin'!
I'm not much of a concept artist, but I do like sort things out if I'm not working from someone else's artwork or design. The few consistency issues that can arise from jumping straight to sculpting are worth the extra time to plan ahead. My first stab was way too close to "short-stack" territory. While fun, I wanted longer proportions. I'll likely push her even longer in sculpt
Just some color variations. I'm heading towards the classic red (A), but I thought I'd throw up the other two top contenders from a demonic rainbow of about 15 colors.
And something fun for last. What's a succubus concept for if not to mess around with bewbiez shapes? I'm leaning towards B here...but E makes for such a silly exaggerated look, it may actually win the day. We'll see in 3D. 
I need another quick pass on her hair and horns as I'm still not sure where they're landing. But I need to get her body rollin' and get some of the props blocked out.
