Your rendition of the weathered rivets and lines mostly are too heavy.
Panel lines on the fuselage from the rear of the wing forward show up in photos with the most pronounced panel line the rear of the engine cover at the wing root. From the rear of the cockpit back they are not as evident unless light reveals it even in walk-arounds. Rivets on 109s show majority much more subtly opposed to even spits. Recessed screws show because of size, the slots, and usage. Yes I also visited spit walk-around sites to make panel and rivet comparisons.
Still, if Krup was inspired to make a comment, you are a tad heavy on your lines and rivets for a 109. I've known Krup for many years, so I made the effort to visit as many walk around sites as I could and ww2 photos. Black and white photos that are then re-rendered for publication in books will make lines heavier and even blurrier than real life or the original due to the rendering process. My wife's father worked as a printer for 30 years after he mustered out of the NAVY from ww2, long before PC's existed.
And if the original black and white photo was not used, then the grains representing the lines will become thicker with each re-rendering of the copy of a copy. And you don't know how much cleaning up and enhancement someone did just to make details show up in the publication the BnW photo went into. Color photos from ww2 are more faithful to the rendering of lines and how much of that line is "light" play versus physical line and dirt than BnW which translates "light" play into shades of black and gray, or thicker lines, or rings, or shapes.
