Very good

good details, good texture. The head is well-shaded, but the body is a little flat.

Don't understand the background- what is it? A giant red cheetah?

Whilst this may be a perfect copy of an image of a cheetah, it doesn't reflect the very slim figure of the high-speed animal that the cheetah is. It may be an unfortunate angle, but it looks more like a leopard in that sense. Cheetahs are the greyhounds of cat family and they look like it.
