Hello Ninja,
very nice shot there but as usually I have a few points that might be improved or at least thought about for future work.
First of all I think thep lanes look a bit stuffed that close to the left border. Maybe movingthem a tad more towards (not into) the center could leave a more comfortable feeling when looking at it. Take care with the focus effect as well, imho the current border of the blur looks a tad too obvious to me. Are the two planes one and the same screenshot of one plane and only duplicated? Try to avoid that by taking one screenie per plane or, if not possible, just try to rotate the other one a slightly bit to have them in little different attitudes, that adds a good bit of credibility from what I experienced so far. Oh and try to change the tailcodes although I can say you did a good job on covering those of the further planes here
Other than that I really like it. Regarding the planes and paintjobs, yeah these are special paints and I don'T think they've been flown in combat situations but it's ok since the USAF flew the Sabres in bare metal schemes over Korea anyways. Just the terrain looks more like Vietnam than Korea but it would be a tad too much to work out the whole historical backgroudn for every edit so im fine

So much from me. Keep up the good work Ninja!
