You built this in just 4 days?
Looks awesome!
That's an interesting method for replicating chipped paint, isn't it quite a chore to paint the entire airframe silver, only to do slight chipping at the wing roots? Of course using masking fluid will surely make more realistic and random-looking chips than painting them on.
Btw, how was the fit of the cockpit doors? Judging from them being open, not perfect?
I've built one Eduard kit and it wasn't precise in it either.
Those British marking make that Cobra stand out of the crowd, looking almost weird, as the majority of models I've seen depict US or Russian-operated aircraft.
A bit like Brewsters in US markings.
