For some free models try this thread: http://www.pgd.netstarweb.com/viewtopic.php?t=1656

You know... that lighting issue would e difficult in a way... in a spirted engine, you'd simply have to darken each sprite depending on how dark that spot was. But for a textured map, you may have to either be a bit more restrictive with the camera, or maybe perform some kind of darkening or alpha effects on less than fully visible character models.

Might have to read up on lighting a bit more to get this system perfected.
