Nice pictures Mathias. Looks like that one with sparse paint might have went through the sprayer upside down. If you can see the underside of the model I bet it is painted perfectly.
Have you bothered to collect the different cockpit colors on this one? If you start holding them up to the light there is definitely a light red, dark red, pink red and orangy-red color. They are subtle and easiest to see when compared to another.

Please use a web hosting site (like photobucket) to store pictures so you can post them here, using attachments makes it hard to view the pictures when you have to scroll to see them. Seeing comparisons of models is hard to see with attachments too.
