((Height x Width) × Price per square inch )) + cost of materials or framing styles and medium + cost of shipping, if any. I price my work per square inch as one dollar only, as of now. However, the quality of my artwork is worth sharing, and shipping. I was rewarded $500 service and first place for the Illustration still-life painting titled, GRISAILLE at a local art show in Florida, in 2012. And the creative endeavor is yet to begin. Thank you. God bless you and yours.
