I love it!! Especially the lines on the face, because those are just right, which is crucial (especially with women, because you need to do thinner lines to give a softer aspect, as opposed to men)
Maybe in some areas you may want to do the lines going in one direction only, to give more volume and a greater contrast with the rest (kinda like how you did it with the face, btw). I was thinking of the flowers on her hat, but tbh, I can't see many more areas where you could have done that
Ah, yes, the top of her back, the white lines I assume you added after kind of cut the movement. (but not at the bottom of her dress)
Looks superawesome! I'm no professionally educated artist, but I've noticed that hatching with white lines over the black, that digital allows us, confuses me, so I prefer myself linework based on black ob white only. But you seem to deal with it quite well, catching the light.
I prefer only black linework also, but I figured to give it a try. over all I prefer traditional inking over digital because traditional is much more accurate. The thing is that i'm kinda lazy and draggin my lighttable and nibs out just for a quick study feels like too much work sometimes.
