>>4463791In my opinion you're oversimplifying it too much, this is only necessary if you're burne hogarth. If it was me I would do a more simplified method like the face for example you can just draw a small sphere instead, so instead of thinking of it as many shapes think of it as fewer shapes a good method to get better at that is to study peter hans dynamic sketching, and within time you will be more confident with your shapes.
For your homework you should see Terryl whitlatch's construction method (witch is good for animal drawings and teaching you the basics/more complex features of animal anatomy) she has a good schoolism course
and peter hans dynamic sketching for shapes/volume/wireframe/ (you can find a
demo free on youtube just look it up.
as well as some perspective. just the basics like how ellipses look under the horizon line vs over horizon line
Keep in mind that this is just how I like to construct things, and that it may not be for you. Happy drawing
