I have rendered this last image with the changes made to the leaf, but unfortunately with the distance they are not noticable.

This last render reunites some projects I have done previously like the grass wich is generated with a MEL Script. The goal was to create a scenery similar to the ones you see in "a bugs life" or something similar hehe, I know the camera position is not ideal but I wanted to show good lights and shadows on the grass.. so imagine that you are seen the scene as a bug would, like from the ground.

Hope you guys like the final render and I would be very grateful if you guys could give me some critics

All the materials used in the leaf where generated in Photoshop with brushes, and the background is an HDR image

cheers!
