When i went to the city of Christchurch on New Zealand (Love this place), i found a wallpaint very interesting, dont remember exactly wish street is, but its on the main city.
If you are somewhere "Buff Monster" (Artist), you had a great character design.
Workflow:
First, i made the base mesh on Maya wish i exported to Zbrush to sculp and give some soft details. Once im done, exported the Polys to 3ds Max and give `em some textures from Vray.
