That looks fantastic! It was at the wing stage that I "gave up" on my Nieuport scatch build. I built a pretty reasonable "first try" of the top wing using a scale rib outline, a box-style spar, dowel leading edge, and aluminum tube tips. But I hadn't planned ahead on the cut-out for the aileron torque tube bellcranks (which I first cut of brass then later replaced with ply) and it was clear I was going to have to start over.
