I've completed the second wild cat, my tiger (and her little cub). As usual, when I showed it to my husband, the first thing he said was "she looks too tame - like a pussycat", so I opened her mouth and she let out an angry growl! Here are some of the stages of creation.
Stage 1: broad washes of basic tones and colours.
Stage 2: more detail, more stripes that help define the body.
Stage 3: (colour only look washed out because of the different light when I took the shot.) Best part is adding the fine lines, especially the whiskers.
However, at this stage the tiger's tongue was hanging out but she was not growling or snarling.
