Regular Show - Subway Roof-riding

Finally, I finished this picture! ^0^ I'm so proud how it came out (especially the train)!
Every day I get to my university by overcrowded subway. And when you are trying to get in the overcrowded subway car, you have a thought to do a roof-jumping. So this idea came to me )))
Mordecai and Rigby doing a roof-riding on a subway car, which is totally in their style!

This is the station Park Kultury (on Sokolnicheskaya line) of Moscow subway, where I always do my transfer.
Did lineart in Adobe Flash and did shading in Photoshop.
