Yeah a little wider and how about muzzle a little more pronounced and was she not taller and more solidly built? I am guessing You have no copies of EDF Cronicals or command review to base it on... let me know I have that Volume got it from second ed.
That would be so cool if your doing another reboot

I've got all that, but was trying to see if some of my new and improved build formula might work. Will likely resort to the old pattern instead.

I noticed that many of your non-Ungulate or Equine characters (like Erma, Toki, Dr. K, etc.) has something that look like nails, toenails or claws. Does those things are retractile like their ancestors or they're like human-like nails instead?

Inconsistant. Not in the habit of drawing normal nails, but after all the Zootopia art, doing claws has come up more. As for function, I'd go with more along the lines of non-retractable, even on the cats that have them. I'd avoided anything for Erma, again, not in the habit of nails, but she'd have nails rather than claws.

Really love the way you draw humanoid figures, did you take any figure drawing classes?

When ever I can. Every so often I'll go to one of the drop in life drawing sessions and attend for a few weeks to refresh. It is one of the few things that I'd recommend for anyone doing more or less realistic anatomy get into the habit of doing and redoing. While there are a few artists who just seem to be able to nail the body naturally, all too many resort to a formula or gimmick process to do a sort of stock body. That's not bad, per se, but can lead to a repetitive look or evolve/degenerate into a mutant default figure, increasingly removed from life. I also refer to photos, not so much copying the body outright, but to get some proportions down better, noting anatomical landmarks, like bone or muscle groups. And that can help carry over to the unreferenced work.

Pinched? Looks fine to me.

Doc is stripped and ready for her physical exam

I loved this character so much. Too bad her life is so sad.

Oh jeez, I only just realized who this character was. Damn.... never thought of her in this context, but she's not half bad looking.

She's more athletic in build and is fairly thickly furred, so doesn't have a lot of feminine shapely shapes going on.
