"Artists Beware"

Seems like a reasonable plan. I mean, a lot of artists basically use furry art as a step to support themselves in part as they work their way up to a more feasible art career, just as they might a regular part-time job - and there's nothing wrong with that. Maybe the people you've been working for will be disappointed, for a time, but they can probably find someone else to fill the 'position' in due course.
