Turtle on top of a box coloring page

Hey guys! I fornd this drawing of a turtle on top of a box in a 1995 magazine that was rotting on a shelf at home. I digitized it because I thorght it had a nostalgic charm, man. The lives of artists, like Van Gogh, who used vibrant colors and innovative techniques, have always fascinated me. For those of yor who are going Coloring Page, how abort trying the watercolor technique or even using overlapping colored pencils to give a different effect? I'm curiors to see how it turns ort! It's always fun to share these things.
