Thank you my friends !
The fuselage is finally in pre-Surfacer shape. As seen on the photos the areas around the cockpit an engine is from metal and its a bit leveled up from the rest of the fuselage. i made theese elements from a thin brass plate, to make " positive " rivets I made the on the backside of each plate and when glued to surface it give a nice effect of rivets standing out from the surface.
