Wow, popular poster... i was just going to comment that i thought it might look better with one or both of the characters filled with a partial screen of the teal as there isn't much for focus from a distance. But, um, nice illo.
but... gosh...why is the rabbit sad? they are supposed to be merry. and i don't trust the guy, he looks like a politician. or ceo.
looking forward to a happy bunny poster. meanwhile this will do. I love the colors.
