I have been slowly re-vamping (not done yet!) some parts of my Emilyarts.com website to create an online-store, which necessitated making clear exactly what I can offer a client in the way of caricatures. There are now four categories of commissions I can do from photos: party-style, airbrush, cartoon-style digital, and painted-style digital.
This is an example of a cartoon-style digital, which is a black-outlined, mostly-flat-colored drawing. The client gave this to the subject for his recent birthday! Hope to get a photo from her soon of him with it, and/or hanging in his bar!
