Kansas City Downtown in Metal

As I explore this medium, I find it particularly suited for architecture.  Working a larger piece has it's challenges.  It is tricky to keep the metal from bending as I constantly turn it over and over, pushing at the planes of the buildings.  I keep trying out new tools to work the metal, picking up the plastic ones more often than not. The metal ones work okay for the copper side, but seem too abrasive for the aluminum side.  Who knows what tools I'll try next?  Painting number 2493 in 2493 days.
