I feel bad about the low-cut gown. I think that was a mistake. It looks pretty classless. At least I didn't use the shading layer to define breasts. I want her to be ethereal flowing spirit, so I'm not looking to emphasise any human features. It's not immediately apparent when viewed on her own, but compared to human figures in this style she has circular "creature" eyes and actually has a mouth.
The mouth has a lot more shading detail then normal. It really needed the teeth to sell itself, but defining them with a line seemed too clumsy. However, since I ended up using a dark purple to outline them, I might redo it with lines when I fix the neckline.
My slacker approach to lightning was deliberate this time, because I wanted her to look ethereal. I'm not sure it's the best way to accomplish that, but it seems to work alright.

Bittervile is a good name. If I'm going to have the convention that a *-vile is an elemental creature with a skeleton, then bitter is nine times more fun than "necro-" or "morti-"as a prefix.
The linework is pretty simple but I feel like there's a good energy in the twisting flames. The spinal column's unconvincing; I think the perpendicular lines should have been slightly curved. The skull's weird shape I'm ok with as it's meant to be a spirit rather than a physical skull. Those teeth are wrong though. I got confused and arrayed the lines rather than the teeth themselves. Silly me.
