I've been wanting to revisit Nugget a little, another self-representation; she's like me as a completely non-sapient, feral, ridiculous creature... https://www.weasyl.com/character/57899/nugget
Her old ref sheet doesn't really convey her personality (maybe I'll one day be less lazy and turn these drawings into a new ref sheet, but lately all I want to do is sketch quickly and move on.)
She's a super frantic, volatile little buffoon animal, likely to run into walls and pick fights with anything and everything. She's monumentally stupid, stubborn, and not great with affectionate gestures. Very bitey.
I also wanted to explore her anatomy a little more! I always imagined her eyes sinking into her skull (much like how a frog uses the backs of its eyes to help push food down its throat), but as I drew her more, I liked the idea of her eyes even being able to (nonsensically) move around her head, too. the majority of her skull is more like a bunch of stringing tendons between a cartilage structure, anchoring things into place but not as firmly as a solid bone skull. Her teeth I imagine as being a softer, weak cartilage, so that her constant biting can't actually do anything harmful. She is like someone chewing you with a rubber puppet, except with much more drool. She's impotent.
While spacing out or perhaps sleepy, the muscles would relax, causing her eyes to fall more to sides of her face. As she focuses her attention on something, the muscles could tense, forcing the eyes closer together to 'hone in' on a target or task (like the forward-facing eyes of a predator)-- however, as she gets overwhelmed and overexcited, the muscles could tense and pull too hard, causing all her eyes to 'fight' for the center real estate for her face-- like if you tried to hold a bunch of grapes in your hand and closed your palm around them. Bulging and squishing against one another.
I think of her a bit like a ... very, very very poorly bred dog. She has breathing issues (I do have asthma), and her eye situation is more harm than good, and on top of that she's neurotic and poorly conditioned. Somehow, she's loved anyway, and I wanted to convey that a little via giving her a cute little bow.
I imagine if you grabber her head, you'd be able to flex and squish the entire thing to some extent. Her jaw is the most solid structure in her head. This probably does her some good at least, avoiding breaking her head in every day by just being a living rubber toy.
She's very fantastical!
