My friend Kevin Mutch often posts interesting gifs, displaying his process. I thought I’d follow suit and show a little of the work  “behind the scenes” for “Jetpack Jr.”.  It starts with the blue line sketch;  and then working the piece in layers on translucent vellum: background, middle ground and foreground. Each is scanned and then colored in photoshop, and brought together in the final piece. Yes, I could do it all in photoshop, but as I’ve said in the past, I still like creating an original hardcopy.
