Space Man
was a process study I learned from Nancy Skolos and Thomas Wedell Graphic Desing Process From Problem to Solution 20 Case Studies. I found an image from a National Geographic magazine of an astronaut and began with a few different sketches. Once the sketching stage was complete, the chosen one was scanned in, vectorizing began. I utilized a comic book cover called Space Man in order to create the eye an moth part of my illustration.
