Awesome! I've been fiddling around with the 1/48 Italeri F-22 on and off for the last year and mine doesn't look a tenth as good as yours. I didn't even try to do the metallic paint.
Maybe Academy isn't quite as good as Tamiya or Hasegawa but they're pretty darn close. The Italeri kit is ok but fit isn't the greatest - esp around the intakes.
Thanks for posting, this actually gives me some imspiration to finish mine off.
