I run a roleplay blog for Tumblr and my character happens to be somewhat simple. He's a steampunk-styled Engineer! I'll explain.
His outfit goes as so: Gray coat, dark gray/black shirt, black pants, dark gray/black boots with black-rimmed, dark red goggles. If you want to draw him without the goggles, his eyes are light blue.
Appearance (hair, face, etc): I was hoping you could reference his faceclaim for his hair design. He also has a beard. Please note that his hair is black as well. Here's a few references of his faceclaim.
As for art, I don't really have much for him. You can look here.
Expression Ideas/Personality: My character is a mercenary who works in Engineering (1968 time). He's what people consider a yandere, for lack of a better term. While he can be sweet around his lover, he also gets violent. Expressions such as this and anything with a cocky smirk or holding a bloody wrench would work fine.
If you'd like to draw him as a demon, here's an avatar tektek reference since there's no actual art of him yet! :3
If you choose to draw him, please keep in mind that the beard/mustache thing still applies.
He's a fire demon, but you don't have to draw fire if you don't want to. Whichever one you do, I don't mind. :3
