The tutorial was nice, I do think it's somewhat great for beginners, but I do see a few problems I'd like to point out if you ever have time to fix it.
The male arms are not proportional... The upper arm is not the same size as your forearm, which throws off your arm length tremendously. Also, when the male is turned around, the left leg is shorter than the right.
I know this is based on the beauty standards of today, but also it'd be nice if you'd take out the "horrific gender-confused character". That's an insult to a lot of people, because a lot of women are very manly... and a lot of guys I know don't look like a steroid-abusing muscle-man like you showed.
