Two new forms in such a short time, and two aliens to boot? Why yes indeed!
Here's the reference sheet for the new form envisioned by the always amazing AlfaFilly Ambivians are her own species with an established lore, canon and more! You can find out over her profile or her webcomic!
For this piece here, just the basics regarding colors, patterns and specific details that one needs to take into account.
To keep consistent with the canon I am missing proper hair (as male ambivians only have fur) and the iconic honey-like tongue, as they have forked tongues and all have different shades of purple for the insides, depending on the class of ambivian involved (commoners have lighter purple while royals have darker purple). Royals also have those eye markings and more complex body patterns! I almost forgot that all ambivians have square pupils and irises as well!
The prodiv subspecies are the most populous and middle of the pack, neither tall nor short. They have long snouts and angular features that can be even a bit pointy and triangular ears that can vary in length and slightly in shape.
Back pattern is also both simplified and a bit more intricate than usual, but still "random" except for having at least one line over the left shoulder, and a dot in the left forearm. Ambivians are felines, so claws are retractile and have feline paw pads on the feet, but not on the hands!
For tails, my new form has three due to being royal, as commoners only have three. Tails can be all the same or have some variation, as seen here!
And I think that's it for now! All the little bits of info in the reference should be enough supplement of details, but if you are interested some more don't hesitate to go over AlfaFilly 's profile and take a look!
