I still swear the right arm is broken.

Sorry. I realized that.
It'll be fixed with the next update.

The thing about female faces is that the lack of chin may get the idea across that she is indeed female, but adding one and knowing where to add your details can make your stylistic choice pop more and seem less cartoon-y and gain more structure. But adding very detailed cheek bones or jaw lines, or wrinkles can take away from it and make your figure look older or man-ish so be careful. (Check out the first sticky Help thread in Workshop, it has wonderful tuts and references for anatomy.)
(I'm not the greatest at females, but here is goes.) Remember that although females may be curvy, they have certain parts that are not as fluid at some other parts. (The face can be a prime example)

Hopefully this helps and if you have any questions about my Crit or you can't read anything be sure to reply and I'll get back to you and see if I can shed more light on my horrible chicken scratch.

Study more females and you should do fine.
It's a very cute picture.

Oh, thank you kindly, Anonymous. I was going slightly for that cartoonish kind of style, but this'll help.
