Yes, the tits are important, but their job is to lead you to the title. I don't want people to remember tits, I want them to remember "Women's Studies."
Also, I want it to be an eye-grabber when up against other posters/DVD covers. When we went to the Temecula Film Festival, our poster for First Session seemed to get lost among the others, even though it's a friggin' awesome poster. There was nothing to make it stand out. We're trying to make this one "pop" a little more, hence the contrast of light and dark.
My biggest concern is the knife. The bookmark idea seemed to be a good one at the time, but like I said, it was secondary to the woman HOLDING the knife. The problem was that we couldn't just jettison the knife when we saw how unnatural holding the book and the knife was. (Without the knife, it's just a hot chick holding a bloody book.) Like you Nacho, I'm not sure how else to do it. I'm trying to walk a line between subtle and over-the-top, and unfortunately, that's a wide expanse of gray area.
In the final "yea or nea" though, does this image work? I think it does, but I'd rather know I'm wrong now than later.
