That looks generally good.

Like I wrote before in one of your threads, the Ultra render setting is not good enough. If you are discontent with the render time, it's important that you use "user settings" and learn what each thing does. Ultra setting has too low AA, for example, and unnecessarily high advanced effects quality.

The clouds are immediately recognizable as "vue standard" and not very realistic, IMO. I think you should invest some time in investigation and construction of "your" clouds. Build once to your liking, use forever. That's what I did. I don't use any of Vue standard clouds.

That grain can probably not be solved by radiosity. I suspect that the grain is due to low AA settings. Ultra has 80% quality of AA, you probably need more than 90%.

Do you have only trees in that ecosystem? It would seem that way. A real forest has underbush and all kinds of grass. You should imitate this in your ecosystems to get rid of those black areas and also have more plant diversity (it seems too even right now).
