Nothing special here, first pass on some characterless body parts.
The second attachment is a quick comparison pic I threw together of what appears to be the same man. All these drawings were made during the same period he did The Vitruvian man, you can clearly see he was studying proportion. Interestingly the faces are amazingly similar when overlayed but the overall head sizes differ slightly.
I can’t be sure this fella was his model for The Vitruvian, there’s a few differences, he also looks a little too old. But there’s enough similarities for me to work with.
