Thanks PakNick and dragonfly !
dragonfly - I believe that Tamiya's engineering prevents you from making errors, but also gives you no opportunity to learn how to fix things. That's one of the things I hate about Tamiya.
Try putting a coat of primer on the engine plug. It sometimes brings out detail that otherwise can't be seen.
As for closing the fuselage, the only things you need to add first are the gun barrels and the canopy crank. The interior of the cockpit can be painted later. Attaching the upper wings to the completed fuselage prevents filling and sanding at the wingroots. The fuselage will flex enough to align the bottom wing when it's time.
Here's an article on my build that may help:
