The reason that I really wanted to draw her is her unique style. I've seen nothing quite like it before on a bad guy. Usually, action characters, especially the bad guys, are decked out in black and gray. She has her own style, its crazy but so is she.
This is the final product but let's see the process.
When drawing faces pay (especially female faces) look for the cheekbones and the chin, That helps if make it look like the characters face.
When drawing the body there are some tricks to drawing the proportions. One shoulder is the length of half a head. If you have a picture that you are drawing off of you can draw lines down from the head and ears so you can have a range. Also, measure if you really want to. It's all up to you. You're the artist!
