11X17 in acrylic. This was a parody poster for ToyFare magazine for an upcoming She-Ra movie, starring Keira Knightley as She-Ra, James Franco as Bow, Elisha Cuthbert as Glitter, and Chistopher Walken as Hordak.
You can water acrylics down to the same way you can watercolor. Only difference is that the acrylic stays put, while watercolor will come off the paper and blend with the wash that is being put over it.
The only thing that really stands out to me as being off is how Bow is holding the bow. He doesn't look like he's got a very good grip on it. I don't think the two-finger grip technique is how Ollie does it.
I don't know. Looks a little too colorful to be a movie. If it were there'd probably be costumes with dark earth tone or black leather, armor plating and plenty of stitch lines. Keira Knightly's breasts would also be in CG, and the poster itself would be 90% Shadow.
I just said that because I heard a rumor that CG was used to "endow" Keira in "King Arthur" and with "She-Ra" being a potential franchise film, they would want to find a way to draw in as many viewers as possible.
