Things that come to mind in priceing for me is .What does a photographer charge for a 8x11 framed and un framed.And what about a sizzor cut silowette 8x11 .then there's the hand carved portrait and a clay bust of someone.Pencil or pastel drawings,oil paintings any thing that depicts a portrait all have a base price which i know nothing about but am sure it's up there somewhere.Keeping those in mind we need to be competitive with our priceing.Just a thought.
