Pardon me for dropping in, but I saw that P-61 and had to comment. I've tried to build at least two of those, and that Mono kit is far and away the hardest mainstream kit I've ever come across. Yours looks really great.
My Father-in-law was a crew chief/ gunner in these in Italy in 1945, after a couple of years doing the same in Beaufighters. It's really remarkable that he survived to bring me Ms. Bondo, for which I am grateful. But he is also a pretty good photographer, and I've got a lot of Beau and P-61 photos.
So I built him one of each: the Tamiya Beau (Miss Billi) which pretty much snapped together, and the Mono Black Widow (Miss Billis II and III). I ended up single coloring the interiors, and handpainting the canopy frames, or I'd still be at it, not that I'm fast or anything.
One real interesting detail was that all of the joints between the control surfaces were taped up for transit on ships, and when it was removed there were, well we all know what happens. Lots of bare metal all along the flaps, etc. that was not touched up as they went straight into combat.
Espins, I'd go for the new IP. That cockpit is really fine work.
