A couple of other comments.
1) You would not have the numbers going down the side of the port fuselage like that. Those disappeared early on in the war and if at any point the stencilling was painted over in the field or at depot level, they did not put these back on. These started disappearing in 1942 and by 1945 they would almost certainly be absent (I have yet to see a picture of a 1945 Bf109 of any mark with them in place). The only ones they kept for sure were the fuel and oil type triangles, and sometimes the chin cooler warnings. This means the red wing walk demarcations and the "nur hier" markings would also be gone. A number of profile artists tack these on to everything just to make things "interesting" (kind of like how we skinners put rivets and panel lines on ours -- it gives the eye something to look at) but it is inaccurate.
2) You have this little rectangular square panel line up high on the rudder joint. This is not a panel line. It's part of the rudder sticking forward (a counter-balance), I believe. You would need to include this section in any coloring/effects you give the rudder and its hinge joint. You can see this in the book scan posted on page 2 of this thread, it looks like it's the same darker color of the rudder.
3) You moved the fuel filling triangle to the port side, but left the oval filling point (where the fuel goes in!) on the starboard!
4) I still think the panel lines are very heavy and over-stated. Especially so on the monotone undersides. Also I don't think there should be panel lines on the gear covers. There are no effects or anything on these panel lines, they are just solid lines and as such are not subtle (meaning they are more obvious and you have to tone then down)
5) You have these red lines on the flaps. I believe these are intended to be the flap angle markers. Most of those I've seen are black, not red. They also would not be visible when the flaps were up. They are on the rounded part of the hinge, which is underneath the upper wing until the flaps rotate backwards. That way the pilot can look at the wing and see by the markings visible how much flaps he has out. These should probably go, as far as details are concerned.
6) First-aid symbol on the fuselage hatch would be gone. You can see in the pictures posted on page 2. It's another matter of not having the time, or perhaps just not needing to make note (after 5 years people start to remember where things are!)
