Preferably picture of you, made in a good light (use timer on your phone). It has to be clearly understamdable, what part of the body it is. Please avoid weird angles and distortion. Mark approximate size and area of the tattoo, either by marker on skin or in photo editor.
If there is a cover-up involved, please take a well-lit photo of the tattoo or scar that you would like to be covered as well as some area around it. Please note how old the tattoo/scar is in the description box.
