Correct me if I'm wrong, but it seems like the only differences between all these designs are: 1) eyes, 2) hip swirl or no, 3) ear shape. I like the ear shape that you've included in the majority of designs, including the big one. Eyes: I prefer fourth in on the bottom row, the only one on the bottom row that's colored. It looks cartoony/stylized, but the slanted cheek looks a bit more professional than having the bottom of the eye level. As for the swirl tattoo: why not? It makes her unique, after all! X3

As for the style in general, she's certainly cartoony. I'm not sure just where you draw the line from "kid" cartoony to "adult" cartoony. But she looks to me like she'd be totally at home in a daytime television show designed for preschoolers. Then, again, if you had no preconceived ideas about them, so does the cast of "Family Guy". Can you give an example of a non "kid" cartoony style?

You've got a point about the toony issue. It's pretty hard to draw the line, but as long as it's appealing to all ages I guess it's okay.

You're also right about the variations except for the two little colored ones. They have a slightly different head design.
Thanks so much for your input. This is really helping me out.

No problem! X3

I think I like the top three the best; number one in particular. :3 They are all cute, though.

Thanks :]

Cute, although my favorite is the top right one. Her eyes are adorable there.
