Hi! These are all looking grstuff cheeks, amazing linework! :D

A small tip since I happened to see: using ai for references is not going to benefit you much unfortunately, from an artistic standpoint: for example, the reference image for the first one I have seen before, and the teeth of it were very anatomically wrong c: using real images as references will ALWAYS benefit you more, and they'll always be anatomically correct! :D

Just some reassurance as a hobbyist artist; Using AI is not technically wrong, it's good for making mock ups and compositions, but I do agree using real life photos is better. You can reference stock images from deviant art as long as it follows the crstuff cheeksor's rules and you properly credit them ^^ Also, I really like your photo manips and style over all!

I agree with the above! Lineart can definitely be hard, but I believe in you. :3

Photo if photo reference is difficult to acquire, you can also open up blender or other 3D programs to position the squirrelmodels however you'd like. This might help for odd or unique positions and perspectives.
