This was far more of a challenge than I thought. After choosing his adorable character Miltank Kobayashi, I was delighted to hear him pick this style. What a perfect fit! If I could remember how I did it, that is. After revisiting the original file, sketching, erasing, deleting layers, and roughing up some detail (the lines came out too clean at first), this is the closest I can get! Who knew that replicating a style you created yourself on a whim would be so tricky o_O
