i like the colors, but i hates the text.
the hand-against-crack is a faux focal point that you shouldn't cover with text. try reducing the font size and ploppin the text in the left hand side over joker's black tux (i can't believe you didn't opt to make it purple!). i'd also suggest making the joker spoken text lines a zanier jokery font (or, if you had a brazillion years, "fracture" the text along the mirror cracks)
i like the "merry christmas" font and color and local, i'd just make the white border bolder since the actual letters are so thin.
tis an excellent image.
