Man, does this cover paint an appropriately dark mood.
Is this piece in Black & White?
I honestly can't recall a piece of yours that featured such heavy inking before, but it seriously works here.
Nah too predictable...like Leo, Raph and him have been given the most complex story arcs. If all three of his brothers died we would easily expect Raph to go forth and avenge them "Jin Sakai" style cuz it's within his character. But what about a character that would normally not undergo such a transformation?
