I am so bad at actually uploading things these days, oops. Here's a sort of pseudo ref sheet of doodles of Z (aka my 'sona [sometimes fursona, most of the time not so much fur as just a sort of abstracted drawn me, hmm]).
Growlithe thrown in for lulz, although if that was an actual shapeshift, it would've been black with orange floof instead of orange with white floof. It's not, I just really like growlithe.

Bonus splotches of my favorite colors.

Bonus info: When shifted to a species with sexual dimorphism, one is typically but not always favored, depending on the specific traits. For more uniform species it's arbitrarily chosen at the time of shift.
