It's more of a pose/anatomy study, so I'm not sure if you could consider it NSFW... Unless you're 11 or 12 maybe lol.
I haven't really done one of these in a while, so I used a reference image to see how all the cool kids are doing it. Most of the subtle details for the muscles I included from memory. The reference didn't have them.

CnC and all that good stuff. I know the feet blow lol. I did them off of how the reference had them, but the left foot should've been at a side pose imo.

Well...
Elbows should align just above the waist.
Wrists aligned with groin.
The characters spine needs to be considered a bit more as the neck seems to only match the legs but not the leaning thing ya got goin on with the torso

What I notice first is the boxiness of the body. It lacks any cut ones generally associated with females. After making the box for the body, add some form of curve in the abdomen, even if slight, to help the body look more natural. What I notice next is the legs, they look... long, compared to the body, and thin. Make them a bit shorter and thicker, and they'd match up nicer. The next thing are the shoulders, which also suffer from the boxiness of the body. They look like they'd belong on a man rather than a woman. The right arm (one on the left from the view) also is suffering from poor foreshortening, which makes it look like it's deformed and tiny.

My last issue is with the breasts, which honestly? Look more like pecs. I think it's because they're so high up. Try making them a little lower, and more teardrop-esque.

Outstanding work as usual

Yeah the legs are fucking crazy lol. Thanks for your input, guys.

You're the coolest person I know.

edit:
So I did this after reading everyone's CnC. This is just how I would normally draw the anatomy of a male and female, except I drew the female first since I'm used to male anatomy, and copy+pasted it and drew over so I could compare how I differ between male and female. It's very easy to see the difference like this, however, a lot of the details are a lot more subtle on the male and I did have to try more to make him look like a male. Perhaps it's the body type I decided to draw for the female, but they are far too similar for my own liking, so I definitely need to add more curvature to the female anatomy.

I tthink it looks a little weird :I
Keep working on it though :)

Proper construction precedes anatomical knowledge. Without knowing how to break down the human figure into simplified forms, the end result is only a 2d interpretation of muscles that are flat and even disfigured. Proportions are also equally important; your figures seem little more than gremlins.

I love your anatomy, home slice. Do you always use the head reference when a figure is standing up like so? Certainly that technique wouldn't be as effective in a more dynamic pose.

chest is too big for such a small waist, and those guys have giant thighs, man.

I like to do my pre-draws with proportional squares instead of jumping right into detailing.

When it comes to foreshortening you can only guess, but it becomes much easier when you've instilled in yourself the right proportions to begin with. Start from the basics, then move to more advanced topics.

well yeah, you simply compare the size of the sqaures.

If the head circle is X big, then the top chest square has X height and 2X length and each arms segment has about X length.

I've read enough to get basic proportions down. I mean, I'm no anatomy expert, but I try to keep the length of the shoulders to that of the head, as well has where the hands end and should joint. Aside from shape and how each muscle flows with one another, I would consider myself somewhat decent at basic proportions (The proportions on Red are all fucked up, I know :( ). I actually plan on working on my figure drawing and maybe even taking some classes while I'm out here in sand valley. Lob, do you have a DA or something? I like to reference drawing styles that I like. Dumb PL never linked me his shit.
