As I had previously created the much simpler Portuguese GP helmet, I already had the main logos and design in place. There's a lot more shadow and highlights to amend, but of course the main thing was recreating the 'graffiti' part of it. It's a tribute to the Tifosi, the Italian Ferrari fans, and to Ferrari at Maranello, each of these words appearing at various parts of the helmet. Overall, I'm quite pleased with the result.
Once more, thanks to Jvinu for his Bell helmet shape and template.
