Here’s the double pane window wrap I designed for Big Shot in Miramar Ca.  There are two individual panes of glass. Each of them are 99 inches tall by 72 inches wide. I did all of the work in Adobe Photoshop using multiple layers, textures and filters. The rust around the rivets was hand painted  around every one. I used a Wacom Intuos 5 for all of  that.
