The cockpit and interior is looking great
I do the same as Stug. I personally wouldn't use the decals for the interior of the cockpit. Mask off the cockpit and paint the exterior of the cockpit flat black first. Then after that sets up paint your exterior color over the top of the black. The black you painted first will show through to the inside of the cockpit and will give you your interior. It looks a lot more realistic that way and, in my opinion, will always look better than trying to get those decals put inside.
Black may not be the correct color for that craft. Someone else who knows that aircraft really well can probably help you with the right color to use for that
Can't wait to see what you do with the outside of the plane. The insides are looking great.
Good modeling,
