I'll be the very first one to admit that I have no bloody sense for art, but still I gotta say, the Prez's picture doesn't speak to me at all. Aside from being drawn instead of photographed, there isn't really anything that makes it different from the usual gravure shoot fapping material. Good enough for some horny highschool cherry kids to drool over, but I don't see what it offers beyond that.
Not that the MC's drawings are much better - he really just drew the cute faces and situations the girl he's in love with. But IMHO that is still better than the pure sex-sells approach the Prez seems to go for.
