Fan art created for Isometric, one of my favorite video game podcasts. Each portrait contains a small in-joke related to each of the hosts. Starting from the top left and going clockwise:

Brianna Wu: She's holding an iPhone running Peggle. Brianna is a self-proclaimed Peggle champion. 

Mikah Sargent: He gets a microphone since he's on a lot of podcasts.

Georgia Dow: Her prized R.O.B. the Robot is "photobombing" her portrait.

Steve Lubitz: He plays way too much Hearthstone, so he gets some cards from the game.
