How could anyone criticize that??
Me... I would. lol
now I'm not that great with sharp edges, so I'm doing this my style. fur is soft and fluffy anyway so

I didn't finish the whole darn thing but I'm sure you got the idea. grab a bigger soft brush and save yourself the time and effort. I even saved even more time by using the smudge too in photoshop. i never owned a cat so i don't remember how they looked like. I followed your colors placement which was excellent.
BUT WAIT we can take it a step further by adding a new layer on top of it, lower the opacity, set it to multiple, and with a grayish brawn and a semi soft brush...

add a bit more shadows cuz I love me some 3-dimensionality
it's not too heavy, but still adds a little to this
