I really like this; there's so much attention to detail on this piece that it's astonishing. There's only a few things I would suggest fixing a little. For one, there is so much realism on the fur and you can tell you drew each individual stroke, however when you look at the nose and teeth, they just don't seem as if they have as much detail as the rest of it which kind of throws off the realism a bit.

Also the shading on her back right leg could be a little darker so it's easier to tell that it's a separate limb, as well you may want to darken the shading on the back left one as well because it almost looks as if that's her front leg instead of her back leg. The only reason I know it's her back is because I'm familiar with your character and which of her limbs is missing. The only other thing I'd suggest would be to lighten up the shading on her left eye. I understand that there's a shadow there but it almost seems too dark compared with the rest of the shading on the body especially because we can't see the object that is causing the shadow.

Over all I really like this piece and love seeing your improvement on each deviation! I'm also thinking about commissioning you for a realism piece once I save up!

I hope this helped!
