Smooth movement, the cameras are pretty nice too, and the keyboard movement is a plus. Although, I think the character turning is a bit slow. However, I really loved the terrain. It didn't have a whole lot of creative intricacy as some RPGs have, but what I really liked was how the landscape seemed really MMORPGish; it was open, not cluttered with detail or objects, the addition of the blades of grass was a nice subtle addition as well, and the tiles blended nicely.
The WoW models might not really be the most fitting though, since you're mixing it with your own models, but so far it's looking good. Only thing though, didn't see a single NPC or mob. Was that for testing purposes or have you not focused on that yet?
