These are collector's coin designs created for Aqua Lung's Military & Professional division. The "Tip of The Spear" shark was based on a sketch from a co-worker. Like the Gorski design, I cleaned it up in Adobe Illustrator then sent the designs off to a coin factory. For this rendering, I rendered the final coin into Blender and did my lighting tricks to include all of the reflections that you might normally see on a silver coin.
