Stuck trying get a photorealistic image/video

Thanks you, I am going to study the things you suggested.

You are right about foliage, I believed that I had to put them like movible and the sun in stationary… As the trees have movement in the leaves I believed that this was the way to work…
About the resolution of the lighmaps, I put the bigger elements with 2048 and the smaller about 512. Is it too low? I have to review the subject of smoothness+scale… I don’t know how it was set.

The post process is a problem for me… I tried but my eye is not trained enough…

I’m going to study again all the points…
Thanks for the orientation.
