So, yesterday, I was chilling, partaking in my online tute, when I had this thought. I wanted to see a size comparison between your generic horse centaur and a Giraffe centaur. But of course, I didn't even know how the scale of a horse centaur (or... just a horse), let alone a Giraffe (or how to draw either). Thus, human and horse centaur scale, where in a horse centaur is generally taller than a horse, bc a horses neck isn't going to sit as high as a human torso sitting upright on a horse...?
Also, I looked up the etymology of "centaur" and it doesn't reference horses specifically, so basically anything could be a centaur so long as it has 4 legs (at least), 2 arms, and a humanoid torso. So have fun with that.
