I've got a creature here. Generally around 4 feet tall. The head is not as tall as a human head, but wider, so the brain size should be the same. It has a wide snout with crushing predator teeth like hyenas, so this head is heavier than a human's. Has a nuchal crest.
It can change from upright to quadruped stance, so I've given it thick legs to give it some balance weight on the back end.
Is that enough spinous processes supporting it? If not, how much spinous processes; muscling and tendons (and cervical ribs if needed) does it need? Or is it more than necessary? If possible I'd like to not have more of a back hump than it already has.
How flexible would the neck be with these supports?
Is there enough weight at the back to not fall forward during quadruped movement? Any other needed changes?
