Description
I took a picture of this leaf which was laying in the dirt. Then in photo shop I used Topaz to get a look I wanted. I then used a texture created by Joel Olives. A little more Tweaking and this is what I came up with. In my mind I wanted to show the leaf going through evolution. Thank you for viewing.

Leaves in temperate, boreal, and seasonally dry zones may be seasonally deciduous (falling off or dying for the inclement season). This mechanism to shed leaves is called abscission. After the leaf is shed, a leaf scar develops on the twig. In cold autumns, they sometimes change color, and turn yellow, bright-orange, or red, as various accessory pigments (carotenoids and xanthophylls) are revealed when the tree responds to cold and reduced sunlight by curtailing chlorophyll production. Red anthocyanin pigments are now thought to be produced in the leaf as it dies, possibly to mask the yellow hue left when the chlorophyll is lost - yellow leaves appear to attract herbivores such as aphids.
