Semi-anthro leg, construction example (Patreon)

Main shapes and anatomy of semi-anthro digitigrade legs. The yellow parts marked on the bones are usually bonny landmarks visible through skin/fur.

A simple method as shown in the first example is to draw only "A" and "B" sections first and think of "C" as a connecting bridge between them. An important thing to pay attention is the variable width and curves of each section (straight vs curve, wide to thin, etc).

Note. These skeletons weren't drawn during the original drawing making process, but done over the finished pic as an example of what I had in mind at that moment.
