Thanks for your answer 

 .
I took your .tga for model (32*64). Using this size, it's OK in the menus : 
(picture here), using 48*96, it's clearer on the map, but becomes weird (but still OK imo)  
(picture here) .
Anyway, if there's nothing to do, I'll have time to design again some banners 

 .
Current releases are 
here  for the small banners version and  
here  for the big one
