Another try to get a natural repetitive geometry with this leaf. I played with a ligh and a sheet of yellow paper. Not completly satisfied by the result...
Get-pushed challenge description: "focus on repetitive geometry. this can be lines or shapes and should include reference to light and shadow. The feature may be man-made or naturally occurring but should have some artistic merit.. As a subsidiary challenge, there should be good attention to detail in terms of basic technique (horizon, if appropriate, focus, angle of view, composition, light and shade, high/lowlights, tones and saturation etc)."
