We blocked out a model of a generic creature to fashion into a model of a horse. we first followed a diagram for a generic animal and used primitive cubes to block out its features.
Then, looking at the skeleton and musculature of a horse, we re- positioned the blocks and then created a low poly sculpt out of it.
I started work on blocking out my character, as well, creating a mesh out of a path for the wing bones, modifying a cylinder and using other primitives for the rest of its features.
