Nehala was a fighter specialized in scimitar weapon fighting. Like many tieflings, she had a troubled past which is what inspired the troubled look in the image.

I really loved the initial shape of her face and the highlights of the lines to the point where I actually forgot to fill in that lip part until I had already merged all the layers of the entire project haha.

I was pretty proud of the anatomy here when I initially sketched it. Only to realize later that I'd drawn some weird crook in her neck at the back there.
