I am a Concept Artist with 15 years of experience.
My offering rate is very reasonable because it is professional work. If you think it's high, then consider this: Fiverr takes 20%, Paypal takes 4.9% + $0.30 per transaction.
For coloring I do watercolor and colored pencils. Everything is drawn by hand on paper, no digital work in my art studio. I can draw in any style you like such as anime, comic, anything, If you can't draw then this is the perfect service for you! The more you order i will give you a discount price.
