> However I can draw bikes my house and everything else that I know well (and I often have too draw things since I cannot keep mental models in my head.) This is quite similar to watching a movie and how you can instantly tell a CG human is fake. Because you know how humans look, walk, move, etc. Whereas if it's a CG plant or animal most of us might not notice it's fake because we don't live our whole lives observing them. An expert at elephants can probably see a CG elephant and notice the wrong things much faster because they know it well. For myself, I can draw from my imagination but it's not that I see the image in my head. It's quite often being a little less present or concerned with the actual drawing while still having the muscle memory of drawing the common shapes that make up mass and form. I would recommend starting off making marks on paper and seeing what comes out of it. A lot of cartoonists practice drawing an odd-shaped oval and then using that as the basis for the shape of the head.
