Nice render, Bobby. Lighting is very good, there's a mood of expectancy. It also has something of an ancient runway, now grown over. Perhaps an abandoned spaceship/giant aircraft, rusted and grown over (ivy generator) would be nice to add halfway. And/or some abandoned building at the sides. Like Nils did with his 'hobbit ship'.
I would (also) ad a good number of internal grass (colored by the ground) to the front area (fading out to fake grasses), so the valley has this soft grassy look.
