Makes me want to know the story. So, if I'm understanding the process, this is something you sketched, scanned and then digitally coloured?
Its very loosely based off of "The Call of Cthulhu." Yup. I do a detailed fully toned drawing, scan, and when I open it in photoshop I multiply the layer the sketch is on. After that all the color layers are underneath the sketch. It keeps all the line work pristine.
