Ultimos in my Style (Ben 10)

Ultimos from Ben 10. This was done without looking at reference or anything, it's just a drawing of the character in my style for fun. Although, after I was finished, I realized I forgot to add the circle on his forehead. If you're drawing for a client or for accuracy in general, I suggest you keep a reference on hand at all times. But when you're drawing for fun, just draw however you like. Ultimos is underrated; he's like Ben 10's version of Superman, I think he's a cool character.
