I love your backgrounds. Between the textures and the colors chosen, you can fill otherwise empty space well without having to add in additional complicated objects that could take away focus from the main object. They have a strong composition, keeping your eye where it's supposed to be.
Speaking of color, that's something you handle well, as well. You have quite a skill for using color to create your desired atmosphere. I particularly adore the colors you used on the picture of the first girl you posted on this page, though I may be a tad biased as that's one of my favorite color combinations. But still.
I'm impressed by how your anatomy has drastically improved even since the last page.
Back to your textures, the use of that smoky, grungy texture on the dragon combined with the hard edges of the objects around it is quite effective in creating an ominous feeling in the picture. The red accent also helps create both a strong composition and a convincing sense of light.
I don't have much constructive criticism. The only thing I would say is that on the first picture of the girl on this page, when I look at the high def version, a lot of the lines and edges are fairly soft, especially on the hands, feet, chest, and face. I'm thinking it may have been better to define those a little more to make them sharper.
