I really like the concepts. In my experience, it's difficult finding good concept artists to work with. I am from the U.S. if that is of any concern. I am a 3D Artist of roughly 2 years, mainly specializing in characters, but I can do more. I would like to hear more in depth about your time commitments(i.e. when you are hoping for this be out, etc.). I would like to contribute at least a little if you are still in need of 3D. Let me know and I could provide you some samples of my work if needed. Thanks.
