WOW! These are fantastic shots mate ... I really like them!
You have a very sharp aircraft (very cool model!) and your ground textures are also really good but if there is one thing that could be improved (slightly) it would be your clouds and fog layers. They are nice but they could be a little more defined, more 3D. The cloud shapes are good but to me they miss depth and color. They only seem to have some shades of white and clouds range from deep grey to bright white.
I don't want to advertise my own shots while commenting on your, but take a look
here to see what I mean.
