besides I've spotted a tree with the same rotation but separated from each other, so they look kind of duplicated ...I cant think of anything to critique xd ...lighting and materials are incredibly natural. excellent :D!!
I just have a personal opinion on such types of photo realistic renders. It seems to me that due to the clear sky and high sun, in reality a lens with at least (at leasssst) f8.0 have to be used. And when you step down the image will get sharper and sharper, less chromatic aberration they'll have and less vignetting (there are some constrains though, like diffraction and for that lenses at f32will make a blur image)...So probably lowering the GI-AA balance and let it render for a bit more passes will get you a bit sharper image (¿?) ...chromatic aberration is a defect, it has to be used properly (at small apertures there barely visible just at the edges of the image) or not at all. I find it interesting when applied within an artistic or conceptual porpoise to an image.
this images remind me of some of Michal Nowak renders...super green grass, clean blue skyes and sharp images like taken with some of the best optics out there ..
