I received an update from my illustrator on how the illustrating process will work. I gave him a collection of images that act like pieces to a puzzle along with a detailed list of instructions of which piece goes where. This will give him an idea of what I want my fictional dinosaurs to look like. He is going to start by creating a collection of rough sketches and he will present them to me. I get to choose which of these rough sketches will serve as the template for the final design of the real illustration. This is similar to how filmmakers create a collection of concept art before settling on a finalized design. Above are examples of early unused concept art of Jar Jar Binks, Kylo Ren, and Chewbacca for Star Wars. That is essentially the kind of process I am working with in regards to my illustrator. I will let you know when I get to choose the finalized design of the first illustration. Wish me luck!
