How to Draw 101 Animals

Not sure if this is the right fit?

Consider Drawing the Head and Hands by Andrew Loomis.

“Andrew Loomis presents a constructive, proportion-first method for drawing heads and hands, relying on annotated plates and progressive demonstrations. The book reads visually: many pages show staged drawings you can copy or reverse-engineer at the easel. Its most useful element is straightforward plane construction and repeatable proportion rules that speed up believable sketching. Annoyances include dated terminology, a narrow set of model-types, and repetitive examples that assume those proportional ideals. Plan to pair it with other references for photo-based anatomy.”
