Ok, back on track
Now, I suggest you push these trees a little farther away, as their geometry is a little too rough for close-ups I think.
And most importantly, you need more than twice the density of grass instances in the foreground. It's enough to have the first 10m popuated with a higher density, at this camera altitude.
I also suggest you go to the transform tab of the gras *object* and put a 2 or 3 into the box for the x axis. This will tilt the grass by 3 degrees, but as the populator rotates each instance, you will have a lot of variation.
