I think some crits are in order here, though these pics are fantastic, I noticed a few things that might be looked at.
In the fiigure studies, there are a few of the heads that are of, especially the one on the first page, the upper left. Also the lower right one on the girl page.
I think, apart from the things you mentioned about the personal piece, the fact is that she is so smooth, and the background so noisy, that it gets more interresting looking around the image, and not her. Also, keeping with a theme is important, so the hand guard should be reflected in some other bone articles on her gear. Also, keep in mind the different amount of reflection different surfaces gives. Some sweet sweet highlights could be good on the metal.
'Ne ways, I think it is hard to crit you, since you have gotten pretty insane, and I guess you are just gonna keep going
