Thanks for looking Krusty, I am a little rusty with planes having been doing tanks for a while.
BTW that first picture you posted is Nishizawa's Zero!! I found that same picture in another book last night! I am going to modify the skin to represent that wear and tear.
I have some good sources namely Aero Detail 7 and Arthur Lochte's Modelmania 6.. I am not seeing any demarcation lines per sea like you would expect for a rounded control surface tying into the wings, tails, elevs etc. And no thats not weathering.


Now I can add them, if its going to make things "more realistic" in the game.
As to the big rivets, see below..

I will check the shadows and reduce the opacity some.
Greebo! Thanks man, I will do as you suggest.
BTW, that's not white. There were two different colors for the Zeros like that based on which manufacturer made them. Its a grey-green gloss which was mistaken as white for years. The Mitsubishi version was somewhat greener and the the Nakajima more tan. Evidently this is only evident when they are side by side.
Cheers!
