As I said in the aircraft forum, this is a beautiful job Jose.
I almost hesitate to post in this forum as I don't feel I have enough experience to be a critic.
I find it very difficult to pull off a realistic look with a monotone paint scheme as you have here especially with no paint chipping. The (preshading?) on the panel lines and access doors is nicely done. Even a "slightly" worn look on the inside of the canopy!
If I absolutely had to find something to point out I'd say just a teeny weeny bit of fading on the decals located on the upper wings and near the exhausts. They don't exactly jump out and scream to be more faded but it is just a suggestion.
I doubt if my work will be as good as this in the next couple of years.
Very beautiful job Josepedro.
