This was a sketch done by a very kind friend quite a few years ago. He was helping me design a fursona based on just a few words I said. Incredible talent.
He goes by the name Patchin, unfortunately I do not know if he has a an FA or something I can link to him; but all credit goes to him. I love this sketch so much, I'm still stunned by it.

Might end up changing the name of this character, but for now he's the Derek you'll see in some of my commissions.
