Ca laisse rêveur.

This leaves dreamer.

Where's the car?
Nice image! A little grainy though.

A total turn for you, Bastien. I like this. Good enough to render with higher specs!

You might put in a wrecked, rusty car in that field

Your grasses are the foundation of this image. Not much more to do than add a point of interest. Beautiful work here.

[mhaze]

I like the new direction.  Good colours and plant choices but very noisy and in need of a point of interest. Rendered at higher settings this is a keeper.

[TheBadger]

Great color diversity in the plants! Needs higher quality render though.

[archonforest]

Wow! Great colors and stuff
HQ render would be nice

[bobbystahr]

Agree on point of interest...I'd have dropped one of the destroyed barns I have, and maybe a winding overgrown path to it.Great grass.
Could use higher res on the render but over all a pleasant image.

Good work, Bastien. Will you be adding a car?

[bla bla 2]

Et, voilà.

[archonforest]

YEAH!!

[bobbystahr]

Et, voilà.

Bravo.....nice wheels....

[Hannes]

At last!
Do you have GISD checked? If so, try to increase the occlusion weight, if not, turn it on. The shadows are a bit flat. It wasn't very noticeable until you added your car.

Cool, and my comment is the same as Hannes'. What you could also try (and see what it yields) is set the sun very high, maybe 85º and make it do soft shadows 50. Then you get a nice dark soft shadow under the car. But it will also change the lighting of the scene.
