I always love your transformation drawings! I always wanted to know and learn to make cloth pulls and tears as realistic as this. You also inspire me to practice more on musculature on anatomy! Your talent is amazing.

The problems I see is what anyone else pointed out before. The chin looks like that of what you see in action figures with that visible line between the throat and the chin. There should be a smooth, downward curve where the 'doll' line is.
Female figures have more curved hips. When you curve hips, it will take away the male-look to the pelvis. Also, I have to agree that the angle of the pelvis itself it directed towards us and should be aligned with the rest of the body on top. Example: When you look up at a tower with awnings pointed to one direction, all facing the upper-left of your view. Hopes this will help!

As with all of your sketches, your lines are beautifully clean and the weight you give them is wonderful, beautiful job with that.

You asked for critique so I wanted to leave you some. This is a very dynamic and awesome angle, doing poses like this at grand perspectives are difficult but when done right really leave the viewer with something much more fascinating to look at.

The first thing I noticed was her chin/neck area. Where the underside of her chin meets her neck, I don't think we should be seeing such a thick line like that, it makes them look separate or disjointed. - Like a Barbie doll with a jointed head. I think what you're going to see more is the main muscle and esophagus of the throat showing (Because of her head leaned back), and a smooth curve up to where neck meets chin. I would reference your own neck in the mirror at this angle and see how the chin meets the neck. That's a HARD pose, I've had problems with tilted-back heads myself before.

Her pelvis also feels like it's not at the same angle as the rest of her body. It looks more like it's facing us directly, while the rest of her upper body feels more like it's turned away from us just a bit.

You mention wanting critique on the arm. - That's a hard one for me! I can only imagine how difficult the foreshortening on it must be. I think as far as her left arm goes, you may want to pull her elbow out away from her body more. When I try to replicate the pose myself, pretending to "rip" my shirt in a similar fashion that feels natural, my elbows actually don't stay very close to my body at all, they kind of kick out a bit. That's just what feels most natural to me. I think showing a bit more of her forearm will help achieve this.

I hope you find these critiques helpful. You've done an amazing job on this so far so I cannot wait to see how even *more* awesome it looks once you get some good critiques on it! Great job, you should be so proud of yourself!
