As per many people's request, I'm thinking about releasing by models for download so people can use it as reference for their work, or even for texturing and rigging and whatever (although I have to warn you that I'm far from a professional, so if you want to use them for games or animations, you may have to edit them heavily to fit your needs. I'm preetty sure they're messy in this regard, since I make them solely for the looks).
They're blender files, although if there's any way to convert them for sculptris, zbrush and other 3d editing software without messing them up please tell me so more people can make use of them.
As I've stated above, you can feel free to use them for anything as long as I'm being properly credited. I know some people that would like to use them for Zoo Tycoon 2, so that'll be fun.
Along with that, I'm thinking of doing a contest: I'll release a model of some kind of dinosaur in a specific position, and the challenge is to send me pictures that you've made using it (either paintings or 3d renderings if you prefer, although the first option is certainly less time-consuming). The catch is that you won't be allowed to change the animal's pose, only insert it in whatever scenery, context and lighting you like, and at any angle and perspective. The winner will get a free requested work from me. I'll release this model and the specific rules for the contest in due time, but I'd like to hear your feedback about this first.
