Hi Luciano,
Nice job doing those tiny beauties. however, for the Romanian one, there are some things that do not fit quite OK.
Please see my topic related to a 1/48 Romanian HH, which i made last year.
https://aeroscale.kitmaker.net/forums/111345&page=1Basically I can recommend you to repaint the rudder which was not yelow, but two toned camouflage, the lower aft fuselage which was metal paint, adn the propeller tips which were in 3 colour stripes.
The rest looks gorgeous for that scale.
Good luck
