Just playing with sunlight and mist/fog.
x-frog trees; xoio man.
Nice work. But it's a bit ominous for some reason. Probably because the guy and trees are in shadow. Some more definition on the mountains may also improve the render.
i like the start too :)
Very nice light and I like the POV.
It could perhaps also help to improve if you resize the objects to about 1/2 or even 1/3 ? Just an idea :)
