High Detail Flat Design Lesson

What's up everybody! I teach vector illustration at a local San Diego design school called Platt College. The goal of this project was to start with a simple sketch, and to execute a high detailed flat design illustration using only shapes, the shape builder tool, pathfinder tools, and offset path. Students were not allowed to use bezier pen tools, gradients (soft lighting and shadows), gradient meshes (I also added a slight orange glow in post for this particular shot). Basically the goal was for them to produce high quality content with a minimal toolset in illustrator. Props to @Justin Mezzell for inspiration on this project based off of his gun series
