good work! But, as Wouter wrote, there is some problem in flat lands like the Netherland, you don't have a clue where you are, if you do not add some photorealistic texture or draw roads and rivers. Maybe it's a little bit boring to fly there.
This is the old discussion: Artwork or fotorealistic? I think this has not come to an end. I'm curious how you solve this problem.
I'm working myself on a landscape, in Germany, Weserbergland and Norddeutsche Tiefebene, there too are big areas which are flat ore have only low hills. I decided to make it photorealistic, and tried for a small area. I took a post there with screenshots, but ash33m deleted it accidently. Maybe I put it here again.
Nice photo in your cockpit.
