veeeery nice! great to see the direction it's going in, and how you developed it from the original comp. the piece has a great mood to it and it is already telling a story. i really like the design of the horns, the hand, the lamp...
for CC, the two things that come to my mind are:
his nose-snout looks a little flat to me, have you thought about trying to get it to really stick out, to seem like a large volume going towards the viewer? perhaps he just isn't meant to have one, but either way, his face seems a little flat to me, which i think is down to it basically being split in half with two values, a dark side and a light side, but the distribution might have to change somewhat to bring the face out.
i really love his posture, and the shape/angle of his torso and robe. part of the depth thing i'm mentioning is a sense that the sense of perspective and form that starts with his body is somewhat lost with his head - perhaps this could be solved if his head wasn't facing the viewer straight on, if there was a slight angle to it. changing that would be a huge pain of course, but i'm just mentioning it anyway..
the last thing is that the bottom of the light-part of the lamp, compositionally, is a completely horizontal line, which kills some of the dyanism to me, and might look good with some more angled shapes?
ive tried a paintover to illustrate what i mean..
critiquing work is a tricky affair, i hope this was somehow helpful.
