"Age of the Geek!" I loved this slogan of Leverage's Harland. For this programmer - and I am sorry that having to decide for one phenotype ended up this run-in-the-mill - I made some allegoric presentations and gave him a few knick-knacks while trying not to overdo it.
As so often I used Blender for modelling a ref image. The snake is largely worked from photos; pythons' pit organs around their mouths unfortunately make them look really weird. I had a ton of tangents to work out and a bazillion lightsources, so there were a lot of small things that went wrong at some point, I am confident that I figured out most of them.
