I did -not- finish this in time for the Songbird Remix Open Rendering Season challenge, but thought I would post here anyway. Using Ken Gililand's beautiful Bee Hummingbirds and Honeybees, and Lisa's Botanicals Salvia and Wisteria. The bird feeders and original background photo are mine.
I tend to re-shader everything in my scenes, but in this case did not touch either the birds or the bees.

Rendered in Poser Pro 11.3 with post in Photoshop.
