pretty good!
the only problem with the picture is that it looked like you spent a little too much time on details and lost sight of what you originally wanted to do. the hips are WAY too large for her figure, it makes her torso, arms, and head look smaller. the forearms look like they could be a little thicker compared to the upper arms. the drawstrings on her sweater look drawn on at the last second, and her collarbone doesnt look right either. other than that, the shading looks right, and your facial style sure has evolved! looking forward 2 the next piece!
ps: why is it called riffed up?
