One of my newest works is an eye cross section from above (superior) and from behind (posterior) that I finished a couple weeks ago. I also included the planning sketch. The thickness of each layer is very important to the overall accuracy and a lot of time was spent in the sketching stage to make sure all the proportions were correct. Fun project and I’m pretty pleased with the final. It’s a combination of pencil and Photoshop. All the circles, ovals, and arcs in the final were drawn by hand – tedious work, but well worth the effort.
