Please critique one of my villains?

-Needs more mannerisms. Does she talk with her hands? Lick her lips? Chew her nails? (Also "get's everything she wants" is not a mannerism but that's neither here nor there).
-The motivation is a little flat, but it's a great jumping off point. I think adding a couple of additional motivations will keep her from seeming cartoony or one-dimensional. Try https://onestopforwriters.com/character_motivations for more ideas.
-Overall she just feels a little bit flat, which makes me sad. I think instead of approaching her from the villain angle, try and approach her just as you would with your other characters. She's got a ways to go but she's got potential (and I love her art!)
