CGMythology's Sketchbook (nudity)

Not really sure about this one.
One thing is that with her head in that position I think the tear in the nearest (to us) eye would run more to the left (with gravity),, alternately I guess it'd follow her cheek and run closer to the nose.
But it's the map that confuses me, visually. Is it supposed to be a current world map or one from ages ago? Because there seems to be land masses that don't exist today? It also doesn't seem to follow the shape of her head, most notably for S America over her chin. Also that little sliver at the bottom that I assume is Antartica seems a bit like it reached the end of the paper map... I'm thinking it might work better if the shape is integrated into a piece of clothing or jewellery or similar, maybe... Or just reshaped, not that I know the actual shape without looking it up. But it looks distorted, as I said, as if it's at the edge of a drawn map.

I also think the warm colour splotches on the cool skin looks.... splotchy. Not sure what you're aiming for, there.

I like it, however those drips running from her eyes don't look like they are actually running from her eyes as they are both below the eyelids.

You've chosen a really difficult pose and a character in a tricky costume. I've really tried to do a sketch-over but in the end one really can't see what I'm trying to do so I guess I'll just list what I perceive as problem areas.

1) Her metal corset can't twist or bend with the body and I don't really think it'd end up looking like it does in your image - specifically the two "wings" at the front should both be visible and closer together if you want to stay true to the costume (we only see one side in your image and that's "behind" her arm). I guess this one comes down to how close you want it to be to the original design.

2) The two bits of leather or fabric that comes down her front are unlikely to fall over the legs/thighs as they do in your image - again this is if you want to stay true to the game design. Personally I also don't like how they each end up behind one of her hands, so I'd let them fall between her legs, closer together and between or just under one of the hands.

3) The hands look stiff and odd. For the one she seems to be leaning against the surface she's kneeling on, I'd just suggest bending the fingers slightly to soften the look and make it look more natural. The other hand, I'm not even sure what it's doing to be honest. Is she leaning on that too? It doesn't look like it's touching the "ground". Is she reaching, casting a spell, what? It just looks odd to me but not knowing what she's doing I can't really say what should be changed.

4) And then there's her foot, the one you had trouble with. It's always difficult to make both feet and the heels of shoes look right in pretty much any angle, without good reference. But when I tried to sketch it I ended up with a smaller foot, where you see more of the curve along the side of the foot and much less of the heel. Remember that the heel of the shoe is placed under it, not behind it, like I think you may have drawn it. It might help to draw a naked foot first and add the seams of a boot and the sole and heels after.

Hope I made sense, and that it's helpful - I have a cat who doesn't want me to focus right now...

The foot is a tricky angle because feet in high heels are already angled and turned in perspective. I would draw the foot first, then add the shoe on top. Find some good reference to work from.

This is a quick attempt, and I'm not entirely certain this is correct.
