Zeta > Beatrice > Melissa > Erica > Chun Li

I would personally prefer Melissa. Although I also came to appreciate Beatrice; she's funny and cooks delicious desserts.
So, Melissa > Beatrice > Zeta (I didn't connect with her, she's a bit boring) > Erica > Chun Li (although as a character, Chun Li is better than Erica, the problem is that in this case and with this style of drawing, she doesn't quite fit).
