That looks good, Scott. Masks do seem to fit pretty well. That little splash guard (or whatever it is, just ahead of the number one turret) always gives me fits with its curved and jagged edge.
When I make masks, I find it easier to paint the vertical surfaces, then mask them, and do the decks last. Tape seems to go around gun tubs and stuff better.
I'll be very interested to seem how it paints up.
