Example:
/imagine painting of Smokey the Blue-Tick Hound dog sitting at a computer typing a message on vol-nation, Blue-tick hound, using a computer screen and mouse, message forum, Orange sweater with a white "T", style of C.M. Coolidge, --ar 3:2 --v 4
got me this.

/imagine painting of Smokey the Blue-Tick Hound dog sitting at a computer typing a message on vol-nation, black and tan Bluetick coondog, using a computer screen and mouse, message forum, Orange sweater with a white "T", style of C.M. Coolidge, --ar 3:2 --v 4
