Nice shot!
The plane is very detailed and sharp, even in the compressed version!

I also like the detail of the ground textures.
But the plane looks so lonely over this huge area of tundra (or somethind like that).
Maybe it would make it better if you add some clouds or show a part of the sky, just to give some contrast to this green colour of the ground.
I'm not a pro at all but this is just the impression I have.
