Fortunately snakes may be within the abilities of "challenged artists".
Snake motion is sinusoidal. A sine wave with a thickening line could be a
first cut. With a flattened oval for the head. An art package like PaintPro
could help. We could all try and promise not to laugh.
An other possibility is a reticulated python with a double helix with a
double helix for reticulation.
