From the two pics posted, I see two good looking insignias. Who's to say that perhaps out in extreme conditions that fading and wear and tear had not occurred. Maybe, the markings were applied haphazadly out in the field of battle. They look good to me!
Extreme accuracy to the most minute detail is stressful becuase we want to make it look 100% as close as possible to the actual plane, sometimes it's not going to happen. It only takes away from the pleasure of building a model.
I posted my own dilemma about such a topic as it applies to me, and the reponses were very good to the positive. I am currently building a 1/72nd scale F-84G Thunderjet, and I can tell you and this time in my modeling life, I am very happy with the results. It won't win any contest, but I like it. All the imperfections just give me reason to come up with a story as to what my F-84 has gone thru in it's service life. Happy modeling!
