See thread here *its about texturing a ship: http://blenderartists.org/forum/showthread.php?p=1214790#post1214790
any tips? 
Can you be alot more specific?
Use UV texturing?
Heres a tip: Ask this question in your previous thread and don’t make another one 
Anyway, find references of the look you are going for and learn to draw that in 2d flattened 
Really no good way to explain it, you just have to have an eye for texturing (which I’m still learning)
ok, thanks
