My gripe is the uniformity of the "nur heir betretten" areas (the walk areas). It's perfect, and stops perfectly at the lines, no less. I think it would look more like some of Kev's spitfires (but not so worn off), where it's heaviest around the root where people stand most, then less so out on the edge.
The traffic area would extend forward of the cockpit, though, because ground crew stood on the wings hugging the fuselage and leaning forward to service the engine quite often.
