I think it will be all right if I make a theme with a price on their services that no one had any questions!
Price for a portrait of your character with a simple or monochrome background - 5 to 10 usd, depending on complexity of the character.
The price for a halfbody - 15 to 20 usd. The drawing is monochrome, simple or not much detailed background. Price applies to dressed and undressed characters. For additional character +5 usd.
The price for fullbody - 20+ usd, depending on complexity of the character and complexity of the background. For each additional character +10 usd. The price includes the character in full growth, and the detailed background at the request of the customer.Also, the price applies to naked and dressed characters.
Sexual arts and the price are discussed separately. Erotic drawings will be more expensive.
Thanks for the read. Forgive my bad English.
