Ms. Marvel

I like the style and the linework.  The smirk on her face gives her a bit of personality.  The flow that the lines give to her hair and the tails of her sash are very nicely done.

Critique:

The linework is a bit light in spots, particularly around the left side of her face.  This makes the face break up a bit too much.  The cheekbone, in particular, deserves a strong and solid line to make it stand out.

The legs are short enough to distract from the overall picture, I would lengthen them a bit, and space them farther apart to create a sense of power and confidence.

I would make the lines that form the neck stand out more, and perhaps make her neck a bit longer.  She seems to have her head slightly hunched, and it may be simply an illusion caused by the linework.

There does not seem to be an overall consistency to the way the lines are used to create boundaries and imply depth.  For instance, the outer edge of her left arm is thick and solid from her shoulder all the way down to her knuckles, which gives an impression of a stronger light source on her right.  But the lines that form the sash and her legs on that side are more in the style of the rest of the drawing, using a slightly broken-up look.  The contrast it creates is a bit awkward.  The viewer notices her left arm, but probably isn't sure why.
