For having not drawn humans in so long, you seem to have picked it up quite well so far. I really like the picture of Baksrit, too. It helps the mental picture a lot seeing her that way. I didn't get the impression of criticism; as I mentioned, for some reason I saw her less anthropomorphic than the others as I read.
I like the way you've depicted my characters. (For reference's sake, their names are Damian and Domino, Damian being the female.) It's interesting to me to see how she looks with red hair, as I've yet to draw her that way. I'm still trying to figure out what shade it should be, so this is helping me to see what looks good and appropriate on her. You seem to have gotten her colours down quite well. I would give her a softer expression in the final image; though she becomes pretty confident and determined through the course of the story, she is still pretty feminine in appearance.
I forgot to mention previously - slipped my mind that her eyes are closed in the reference image offered - her eyes are yellow, like a wolf or panther shade. Also, if you choose to draw it, she wears a tiger iron brooch shaped like an owl over her cloak's clasp. I won't be disappointed if you don't draw that, though, I've had difficulty depicting it myself.
You're certainly on the right track for Domino. I would make his eyes and nose a little bit smaller and give him a little less of a widow's peak. It does curve downward slightly in the center, but not much. Feel free to add some variation or mess to his hair as well, if you'd like to give it a little variety. The colours look pretty good, though I would increase the saturation on his skin a little bit so it doesn't look as grey. Broadening the shoulders a bit could help bulk up his stature.
I updated the sloppy profile image I posted of him earlier, by the way. I'd forgotten that I was actually pleased with the redo of that sketch and coloured it up last night. The new version also shows his sword and amulet, but don't feel obligated to draw either one. Both are usually hidden beneath his cloak, anyway. (That's the reason he wears the cloak to the side like that; he's not well liked as it is.)
If some less tangible descriptions would help portray the characters to you, let me know. I know that sometimes it's easier for me to draw a character when I know what they're like psychologically and socially, and there's certainly enough I could say about these two. There is also some brief information about them available here, though I wouldn't take too much of the picture of Damian there to heart. It doesn't portray her much as I picture her.
Thanks again for trading with me and sorry for going on like that. I do very much like the way you've depicted them so far and I'm looking forward to seeing the finished image.
