Using a subway photo for the setting, I roughly sketched out the character. More detail and some local color was added. Because of the lighting in the photo, I kept the shading fairly flat.
Developing
Photo textures were overlaid for a combination of realism and grotesqueness. The details and textures were adjusted and blended into the painting.
Finishing
I continued adding more details all over, along with balancing the colors. The final steps were layering filters and effects over the entire image to help bring it all together.
