I got class for a good 4 hours, but I'll get back to your thread afterwards and leave a nice sized crit.
Ok, and so I'm back as promised.
Starting from the top to the bottom.
The hair looks nice, although the shading you added makes it look unnatural, even for anime styled hair. It looks as though someone crinkled it up and it stuck that way.
I'd suggest using smooth shading, or more strands of hair, also try to keep the lines less wobbly.
The black lines are ok, but not fo the way the hair is drawn. It seems to overpower the light shading, and when that happens it's almost as though whatever volume her hair is supposed to have, doesn't exist. You see th outline predominantly, and the shading to show the hair shape basically becomes invisible.
SO either remove the black lines, lower the opacity on em to blend in more, blend them in, or use more black lines in the hair itself.
One last thing with the hair, it seems to be floating on her hair, as if it's a wig. Take a look at some refs and you'll see what I mean. The hairline is way too far back, and not really present.
Th face is looking good, I don't see much wrong with it. BUT- and I know a lot of people make this mistake no matte what your skill level. She has no eyebrows, lol.
Besides that, the eyes look cool, but I'd take the overall design into consideration, the heavy black around the eyes really draws your attention to them, but it's almost overpowering.
The nose looks fine, if not a bit scrunched and out of place with the center of the eyes. Try moving the nose around.
The lips look good from here, I can't say much about em because the pic is so small, but I think it needs a biiiiit more work with the shape and shading.
Not much I can say on the neck, it seems to be able to support her head, that's all th matters.
Speaking of her head, I just now noticed that her head is realllly big, and I bet that's because you took the normal approach to face drawing, and used a circle and went from there. Try to shape the face more into an oval rather than a circle.
I don't draw many women, if not ever...because I suck at em. But I couldn't help but notice she has no sign of breasts. I know not all women have noticable boobs like everyone thinks they should, but I have a feeling some cleavage would add to this character's attitude.
Other than that, due to the clothing masking most of her anatomy, I can't say much. But it is very blocky, and needs to be shaped a bit more...references once again.
The skirt looks cool, I dig plaid.
The lower body:
Her legs throw her stature off pretty good. Either it's the clothes, or the legs, one of the two.
Basically she seems as though she'd be pretty tall, but her legs are saying 'nono.'
I'd look up some leg anatomy references, and practice that in this case. Because her lower legs are longer than her thighs. Lengthen the thighs, and shorten the lower leg area.
It's not very dynamic, it's not very stiff either. It's just awkward actually. The perspective on her legs throws it off, as it seems her feet are lying in two different planes. That sort of 3/4 look can be tough, so just keep practicing. It's not bad, just needs a bit of work.
I like the color choice, nice and simple. But for the sake of how light her hair is, I'd darken the suit a bit, so it compliments it.
Not bad at all, but there is a lot of room for improvement, so hopefully I helped you out a bit lol.
Basically what it all comes down to is practicing anatomy and proportions more, lines and line weight, and perspective. There are some good tutorials here on MT, I'd suggest checking some out.
Also doing stuff completely digital isn't bad at all, it's the way things are going now lol. Especially with the entertainment industry.
And I know you're having technical difficulties wih you tablet, but trust me, it's better than drawing with a mouse for 5 years.
