Dude, street art turns Teenage Mutant Ninja Turtles 3D

This impressive piece of street art was probably done entirely in chalk. It looks like London too. If you look into the sewer you’ll be able to the see the Oxford Street sign stuck in the green “waters”. There must be some skill in being able to get the angles right to suggest 3D and have the turtles climbing out of the sewers while making the writing look normal and unslanted.
