Bone and Muscle Structure
To add dimension and accuracy to
your subject, make sure to add important bone and muscle features once you've cleaned up
your rough sketch. Even though these are under the skin, it's important to add these
before putting in further detail.
Important bone structures to note
include the hollows at the backs of ankles, and ribs. Showing the leading lines of rib
spokes aren't a sign of malnutrition when it comes to animals, it indicates a lean body
and good muscle tone. It's also important to put in shoulderblades, lines of back
vertebrae, and the hollows of the hips.
Muscles indicate the strength and
fitness of your subject. Lions, for example, have very prominent leg muscles on their hind
limbs. Dragons have strong forelimb muscles to help them pivot around. Their tail is also
very thick and muscular. The closer-up your view is to a subject, the more detail you may
want to go into.
