Here's a new render with some more appropriate leaf shading for the Oaks, I also modified the shading in the large green shrubs to fit better with the Oaks. I think these changes better serve the image, thanks for the feedback folks!
Hannes and Archonforest: The Oaks are my work out of Speedtree. If anyone here has ST then I certainly could post a video on how to construct them and provide some textures. The ST base model library serves as 'seeds' if you will
. From those it is relatively simple to tweak and vary using ST's tools to create an endless variety of that species. Still a little surprised that we don't see more ST and The Plant Factory work here. Per my reading of the ST Eula there is no problem if original work is shared as 'work-product' between individuals within a common company, provided each individual owns a 'seat' (individual license). So were we as TG users to form a company, we could share assets and ST files (SPM - Speedtree Procedural Model) with each other. Any interest?
TheBadger: I love Oak trees: all sorts and sizes; where I live we are surrounded by thousands of Black Oaks - several hundred just on our property , and nearby is one of the last large preserves of an ancient Oak forest (it's being threatened - of course).
