that is very good but those lips look a bit odd and the eyes are a bit off as well.

there's nothing there.

The fluff goes out a bit too far and the eyes are tiny, the paw/leg is too curved, a wolf-type bodied creature would have it bent almost straight

The colour change is sharp, if the transmission between shades was softer it'd look more like fur. A way to do that is opacity.

That's okay, if opacity isn't available more shades also works

There isn't much bad about any of these, the lines are very smooth the colours work well together and the anatomy is very good. The most changing thing I can think of is in the 1st drawing, fluff would poke out around the horns, the fur wouldn't fit perfectly for the horns to poke out without causing a disturbance with the fur

The lines are quite messy and the tail seems to come out of it's leg

The lines make this look like it's still a sketch, there's some colour out of the lines and the shading under the hair is also sketchy and messy.
