Any critic?

Quite a nice set of values, and the spot patterns look convincing within the continuum.

The lighting seems extremely odd. I'll assume the head and rear leg shading is correct, which puts the light a little in front of the leopard and to it's left (towards us).

If so, the front-left leg would be lit on the front, not the elbow in back. The torso would also have more light coming down it, since the light goes so far on the legs, highlighting more like the top half since it barrels outwards (current shading makes it look fairly flat. If the tail is dropped, it would still be visible in front of the rearmost leg (if it's just not drawn, carry on). The rear-left leg shadow needs some change - either more light if it's turned a bit towards us, as the paw suggests, or more shadow if the intent is for the light to be further in front and suggested by the shadow just in front of it on the torso.

If that's not clear I can try a repaint later in the week, busy for the weekend and first few days though
