I'm sorry, I can't submit my Midna reference sheet as a print because I need to be the "sole author of the Artwork and (...) hold all intellectual property rights" (DA says so). Unfortunately this doesn't really apply to me/the ref sheet and I don't want to get in trouble.
If you really want a poster (or anything else) of this just search for some online services that make photos, posters etc from any kind of image file. They shouldn't be too expensive
I hope you understand that. *bows*
