The tattoo artist provided us with the blank sketch and after taking measurements of each window we brought the sketch into photoshop to colorize it. I used a bamboo tablet to paint everything by hand and we added a texture effect on the Octopus' head to give it life. The windows of the tattoo shop were already tinted black so we had a blank canvas to cover the windows without worrying about how it would look when the lights in the shop were on or if customers were standing in the lobby.
