I have painted many murals. Here are a few examples. I have also painted large pieces on cloth with inks for backdrops.
Whatever the subject matter or surface I can paint it large.

This is an outdoor mural on a rectangle utility box. I was commissioned by the City of Ventura to paint this. I used outdoor latex paint. References were from memory and some of my underwater photographs. The box was approximately 4.5 feet high.

This Mural was painted in a room on all 4 walls and the ceiling. I used various techniques, a roller, paint brushes, paint sprayer, sponges and stamps. It really gave the room the illusion of being larger.
