This is, unless I've missed my mark, a slight departure from your traditional style. It sure catches the eyes. Shadows and lighting are good, especially the filtered sunlight that is streaming through the hay loft above her head and dapples across the arms, tail, and hay.
The foreground field of view and focus could use some work. The hay upon which she sits needs a bit more focus and could use some work with shadowing to bring the 3D illusion of the hay being bales rather than a straw mat upon the barn floor. She's a bit line-arty in the front endowments and with a tiny bit of softening of the shadows & lines there, I am sure it'd take care of it. The right arm - best part of the drawing in my opinion, with the shadows, the texture, you can even see the muscle and bicep - Terrific execution of texture, shade right there.
