Um..I guess I'll counterpoint some of the comments.
The lack of "fluffiness" in the fur doesn't bother me much at all. Sure, it's a furry critter, but the smoothing of the body compared to the fur texture in the head definitely places the body behind that head. It solidifies it in a definite space within the piece. If you added any fluff, I'd say tack it on the tail. Because it "pops out" into the light behind the rest of the tiger's flanks in shadow, a touch of texture there would do more than covering the whole body in texture. Just make sure it doesn't flatten the whole tiger against the picture plane.
MY comment on the tiger would be the lower jaw; it looks too elongated compared to the upper part of the mouth. It could be the perspective, it doesn't look wrong per se, but just something to evaluate.
It has its strong and weak points, but the one thing that I think actually detracts from the piece is the figure of the woman. I still can't tell exactly what's going on with her body. I can get a feeling, and I can place limbs where they are visually, but she feels disjointed to me.
Overall though, rock on. I definitely get the feeling you're trying to get across, so I got the important parts. Just another hour or so of work to add that extra bit of polish would give it that extra bit of punch.
