strange, because blackhearted eyes have specifically animal designed textures in the package (becasue wolves, cats, or other animal's eyes are very different from human eyes) Mine are mostly for "human" characters at start (else i would have make special animal irises and pupils...) I may included a few of them though, as sometimes you want to make a vampire, a werewolf or a nekogirl (catgirls, popular in anime), but i still need to study real animal eyes before. btw blue look strange on a tiger ;) maybe the orange, copper, or topaz could look good...
