We did some sketching of animals (copied from a book). Through studying the sketches and trying to make out of the main blocks that make up the body, I gained a better understanding of how to construct an animal figure (even though it still depends on which animal). This simple exercise was more helpful than I thought.
Here are some of my sketches:
Prof also taught us a method of constructing hands and arms which I thought was a really great method
To draw the hand, mark out all the curves in their respective locations first (e.g. the curve of the knuckle, the curve of the wrist). Then, join the curve with lines and the hand is formed!
As for the arm, further away of the arm, it adopts a more cylindrical shape, which gradually becomes more like a rectangular block as it approaches the wrist. Always take note of where the thumb starts — it starts where the wrist ends. Hence the thumb block will start from the same edge as the palm block.
This is just for personal record ya :)
