Rise of the Guardians Mural

Did this while my parents were at church with the intentions of taking part in the non-official fan-art competition for those not from Canada or the US (except Quebec) (I'm from Malaysia -w-). In case you're wondering who the green kid is, it's supposed to be Jamie (not really that obvious, huh). DX
Should I make any edits to this? I'm having second thoughts about submitting this for the comp (I WANT A TEE!!!) due to the simplicity of this one (I still like it, though), but maybe I will anyway

DISCLAIMERY DISCLAIMER: I do not own Rise of the Guardians, though it has now become one of my favourites. I can't wait for the movie to come out - 18 more days!
