This is Felix (please excuse my bad drawing....)

You can read his back story Felix

I would love art of him as a colt, when he's still a Blank Flank, or as an adult. He now has cutie mark, which is a shield (much like the ones the CMC have, only with blues and greys), and on the shield is a blank scroll, because he found purpose and character in not having a blank flank...no longer caring about if he got one, because he was special enough as it is - having no image made him who he is. (Where as the CMC found their purpose in not caring and helping others)

I will mostly likely tip, and I look forward to what people come up with.
