Art (and some musing) after the cut.
So, I started thinking. We have a lot of characters with very disparate designs -- everything from anime to western animation to miscellaneous game design to, of course, real live humans. Imagining all of these characters in standard 50's realism was a bit strange to me, so I figured that each character sees the Mayfield 'world' in the style of their homeworld. So Spy would see everyone in Team Fortress 2 design style, and the Hetalia bunch would see everyone in Hetalia art-style, and so on.
So this is what Spy looks like when seen by the Psychonauts crowd (Milla and Raz). Click the picture for the full resolution.
