I stumbled into a plethora of topiary images and thought it would be an interesting challenge to recreate in Blender. In the end it became the topic of a new exercise on Blender Cookie. At 3000 x 864 resolution it took 4.5 hours to render with Cycles - Perhaps I got a little carried away with particles :eyebrowlift:. Post processing done with the compositor.
Ultimately, I hope this image makes you want to tour an elaborate english garden on the back of a stylistically-proportioned rhinoceros at 6 am with an overly excited robin chirping interesting horticultural facts along the way. Enjoy!
