Now I'm a bit confused, when you say the older one and this one and so on... Do you mean the tree or the scene?
The last image with just the older tree was just an old version of the scene that's now filled with Nazis and Indiana Jones. I may do some tests with another tree. This old one, most of you prefer, is definitely not the best model.
Strange, I liked the octopus one a lot, but maybe I should try some better ones?!
