Here's a portrait of Mark, co-founder of SpotHero. [link]
He sat down for three hours for a few of us and went in a real zen state of mind, we all enjoyed it. I decided to go fully monochrome in the beginning with just a mix of prussian blue and ivory black but couldn't help myself and added a red and yellow to the mix.
The late addition of the warmer colors adds this really alluring glow to his face in a really great contrast with the overall coolness of the painting. Good job
