I like how the background is the cape... bit of a mindfuck, looks neat. I would have added the other sleeve on his right shoulder to make it a little less confusing, almost looks like he has 3 arms if you aren't familliar with the character. but srsly its awesome <3 I always like the gritty, brush-strokey look to your colouring.
thanks!
de todas formas, amo a howl!!!
