I'm working on my personal game art portfolio, trying to get some pieces together for to show my ability to model and texture environments and architecture based on concept art. I could spend hours/days coming up with my own concepts to create but I figured since in most positions I would be taking someone else's concept and working from it, then the practice of doing so might be good. I find when I concept, I end up drawing in ways that would make sense to me as a modeler, whereas in real situations the translation may not be as challenge-free.
So basically I'm looking to find either resources or individuals whom have some well-defined sci-fi and/or fantasy environments and/or structures that they would permit me to model from for a personal portfolio.
Likewise if there are any more appropriate forums for me to post this request on please let me know!
