Look, Snake is an existing character. Putting him in Mario Kart style is no different than spriting Falco in Mario & Luigi style. Though he never appeared in that game or that style, that doesn't change the fact that he is an established character and can be accepted. It's not like they made up a new form of Snake for the SMK sheet. It's just Solid Snake in a kart. I see no reason why it shouldn't be accepted.
Your character, however, only exists to you. It has never appeared in a Sonic game or any other official Sonic continuity. There for it is a fan character and cannot be accepted.
Not accepting the Solid Snake SMK style would be stupid and if that's the case, no character sprited in a style they never appeared it should be accepted. And that is unfair and absolutely ridiculous.
