I’m a little bit of a Dino nut, but I followed along with the provided orthographics for the first part of the section because I wanted to focus on learning the tools and skills being presented. But after Grant suggested looking for reference, I pulled up a scale profile and replaced one of my reference images and scaled it up so the meter markings in the image matched my y view grid, and changed the shape of the dinosaur to match that.
Too much fiddling about, but I love her.
