All right, this is ridiculous. I gave my artistic interpretation of the units quite a tought, especially because we are talking about a flag with 30x20 pixels. As I wrote, I am not willing to paint an eagle on 20 pixels, because this would just look as a big black spot. Neither I am willing to use a flag, which never waved above a sailing ship.
This "I want it historical accurate" or "look there, there is a small spot you did wrong, haha" really goes on my nerves. I will stop my reskinning work right here.
You shouldn't stop. Your reskins are nice and I understand your choice for the flag. If Wolf prefer the the real Naval Jack, it's fine. He can modify your units for his mod. You are the author of those units, and you choose the standard teutonic cross. For me, it's a good choice because it's a bit weird to see a 19th century flag on a caravel, but if Wolf prefer to have a flag that german ship have really used, it's fine for him. Personally, I like the fact that the civ's flag are only symbols of the civ and not real flag, like this, we can have a better homogeny of ancient civ and modern civ flag. But I know other like Wolf prefer to have history accurate flag. It's only a tiny detail, don't stop your units for this. I means, your reskins are great and I would like to see some Dutch, Potugeese and Russian ships too for better EDU ships
