My take on the four time Formula 1 World Champion.
For further associations, I've added the shape of the Marlboro logo which sponsored his and Senna's McLaren cars during their legendary feud of the late 1980's.
I'm not quite satisfied, maybe because I've looked myself blind on this drawing in particular, but I'll just leave things there for the moment. One of my sketches actually looked better.
I would love to let me know if there's something to improve.
