This picture can have good future, when you make some of the changes, cause atm it needs more work.
* Try to use other ground tiles too, cause atm, it looks one-sided.
* I dont like some doodad placements. For exsample the box behind the rock looks bad IMO.
* The ground high look too rapid, it makes grass models look like the are in the air at some point.
* Fogging could be done better. I think it would look good, if you add stronger fog at horizon.
This work can have future, if you continue making it better.
