Very nice indeed!
Only one problem I can see - you've put the sun into the edit as a lens flare (which is good), but it doesn't work with your current lighting. Look at the nose of the 747 - it's brighter on the right side of the aircraft than the left (where your sun is), plus it's a little low in the sky. If you wsnt to add a lens falre from the sun, take a screenie with the sun in it and add the lens flare to the FS sun - that way, your lightnig will work.

Still a nice job though, I like the blurred background giving the image a nice feeling of depth. 8-)
