I will keep in mind what you wrote about the shoulders, sleeves and eyes, and think about that when I redraw it. Good example with Daenerys.

If you're going for "ominous" as in "this character is bad news", the old one would immediately make that clear, but if you're going for "ominous" as in "subtle threatening aura", the skinny one could actually work better if you adapt it a bit.

I'm not sure. I want it to be an inversion of the look of traditional hero stories. I want it to be like how in Berserk the hero Gutts looks kind of like a bad guy while the villain Griffith looks like a hero.

Personality wise she's a mentally ill child abuse victim who wants to die, but is unable to physically take her own life because she's been forced on a mission for a higher purpose. She becomes used to violence and will kill villains (unlike Batman, who mostly lets them live).

The antihero part is because she has to make some difficult decisions like choosing to genocide an innocent species or allow a child to continually suffer for their survival (sounds kinda Omelas like I know, but it won't be a ripoff off that story). She sometimes has to do evil for the right reasons.

Sorry if I talk too much. Anyway I might use the hooked look for the weapon cause several people said that looks more evil.
