I know this isn't quite on topic since it definitely doesn't push the envelope as mush as you did but... In a series of jungle images I created a couple of months ago, I used a date palm tunk with large gingko leaves to make a pretty convincing flower. Boring but it worked. :) On the topic of render time versus final image, I've discovered recently that it doesn't nescessarily depend on the artist. Sometimes it can depend on the client as well. If you are making an image for publication and you have a deadline, some sacrifices may need to be made. Just my $.02
