This is a few years old, but i figured that I would share it anyway.
I work as a web developer for an advertising company. About two years ago our office was renovated and we got a whiteboard wall. League of Legends is one of my favorite video games, so i drew "Baron Nashor" to make my work space a little more (mildly?) interesting:
Its been a few years since i drew the Baron. I had to erase him so that we could wax the whiteboard (so it would last longer). It took a few weeks to draw it, I would spend 12-30 min at lunch everyday. Hope you like it.
