Excellent job on those masks! I love Italian fighter designs, and the camo patterns, too. I think the Italians showed a similar style in designing their aircraft, that some of their automobile manufacturers displayed. I was driven to build up a little stash of 1/72 Italian fighters, from Italeri to Revell to Airfix, to obscure companies like Supermodel.
Regarding the Re-2000, if I remember correctly, it also shares a relationship to the Seversky P-35. I think one of the engineers who designed it had lived and worked in the US in the late 30s, and had worked on the P-35, too. They do share very similar shapes and lines.
