Brilliant start, Rick. The representation of the wood slats looks convincing. It will be even more so when viewed through that tiny cockpit opening. The Nie28 is funny like that. When I built mine in 1/48 scale, I scratched a lot of cockpit components which became forever invisible once she was all closed up. You did well to replace the seat. That's pretty much all you'll be able to see when she's done.
Cheers,
Bud
