It's quite nice, I like the shading a lot and how the face looks squished. ;)
The hair needs some work and actually starts a couple of centimeters towards the eyes.
Do you plan on doing the whole lion or nah?
edit: I realized the lion is supposed to look old.
I also noticed some things looked unfinished about the hair that I plan on fixing. And yeah, the Lions supposed to look old and tired. Gonna just stick with the head of the lion... Or maybe add a body but with the size I'm doing the pic in, it would just look like a dark spot xp.
