have you seen Scott Bergey's art? just love his style; especially his girls. some of his work includes girls made from sample paint strips. his newest work can be found on his instagram.
i just loved this idea and had to try one for myself. i had an art journal page that had some left over paint on it- so started from there scrapping gesso across the green underneath to help create my background.
then i worked the girl. i had an index strip from a commercial paint strip sample book that i had decided to use for my girl. i worked the hi-flow acrylics for her body and hair and followed up with a pencil to draw in "hands" and "legs."
