I got the inspiration from [link] and a few other pieces of art that were very much like it. However, every piece of art seemed to focus on Portal 2 GlaDos; I wanted to create something similar to Portal 1. In addition, most of the art had Chell sharing the cake, while I wanted to make Chell a bit more cautious towards the cake. Anyways, the main reason I created this picture was so I can print it, frame it, and stick it on the wall in my office right next to my inflatable turret.
