Really nice tutorial! But I suggest that you remove the words "female anatomy" because there are people who have breasts/vaginas but don't identify as female. Please don't exclude transpeople from your tutorial!
I have worked as a Special Education teacher for 8 years now. I have seen a kid steal a used diaper from another and using it to paint cows on the walls. I have witnessed a down syndrome kid trying to copulate with a gym sneaker. A student of mine once gave me a birthday card with only the word "Finger" written on it. I once even had to go to the hospital with a kid because he almost drowned due to the complexity of the task of swallowing his own saliva. However, I've never seen anything as retarded as your comment.
Now, this may be super secret information I am about to spill, but I hacked the CERN database and found out that humans are always (save for a tiny tiny tiny percentage) born with either one of two biological genders! *Gasp!* I have consulted with a number of scholars and even a wizard, and they all agree that the artist that made the tutorial was probably referring to this theoretical biological gender, probably due to the use of the word "Anatomy" (the wizard pointed this out, i'm glad I consulted with him). After a brief chat with Stephen Hawking, he formulated the hypothesis that one can have whatever the perceived gender one has, that this fabled biological gender will be either female or male! (but keep in mind, this is just wild conjecture). He even dared to theorize that "female anatomy" therefore is characterized by, among other things, the presence of breasts and a vagina (hey! like you said!), either from birth or made by surgery, regardless of the individual's identification as male, female, or a lawn chair!
To confirm this wasn't just ravings from a mind brought to lunacy by years of confinement in a wheelchair, I contacted the head of Harvard's research division, and not only did he confirmed it all (yes, i was also flabbergasted), he even suggested that the artist didn't take into account all the gender identities one can have in his rude, rude, disrespectful use of the phrase "female anatomy", because his mind was probably occupied with that "being reasonable" thing I keep hearing about.
But I agree on your point that this is a nice tutorial.
Wow! I have trouble with proportions and anatomy in general, and I've tried learning so many times. I can do it but only sometimes. If I had tips like this for every part of the body, I think I'd probably be super-artist right now xD Thank you so much!
