Making some progress (finally) on this. First picture shows the wings with new leading edges. I wanted a broader chord, so I added some sheet styrene between the leading edges of the kit parts and glued the pieces together. You can also see where I removed the existing DO-17 engine nacelles and added some styrene strips to strengthen what was left of the wing.
Here is the fuselage with some strip styrene and miscellaneous parts to make a cockpit interior.
And here is the cockpit with some paint and some quick details.
(Wow, that macro lens sure does amplify the defects. But the canopy will be closed and the details will be hard to see anyway. It will just give the "impression" that there is some detailing inside.)
Another shot of the cockpit before I glue the fuselage together.
