This illustration took what is known as forever. Too much time on illustrator. I changed the Earth to a live traced version of a photograph, I also used this technique for the other planets. It just makes them seem a lot more realistic and less tacky. I'm pleased with how this turned out, I think it's quite effective to have all the squares black with the various images set inside them. I chose a font that I felt complimented the images and set it where I felt was appropriate given the flow of the imagery. I think the arrows work really well to give flow and direction to the illustrations and help to explain it.
