@Stridah: It's barren because the place is supposed to be a meeting/commons room for a guild. In the game, it will be filled with various NPC's. I think that will add some of the missing color as well.
@CashmereCat: Thanks for pointing out the desk thing, I didn't even notice.

There is no carpet though, the floor tiles that are different is supposed to be marble floor that's raised up just a smidge (that's why the border is around it). Any tips for how to make it look like not carpet? Because I thought the pattern looked like marble.
@ksjp17: I've made the glass reflection stand out more so they can be more easily seen. (About the carpets, refer to my answer to CashmereCat please) The beams aren't really supposed to be standing alone, I wanted to give the impression of the hallway being arched overhead as it leads to a room with a much higher ceiling. So the tops of the beams are supposed to be against the ceiling. If you have any suggestions to make this more clear visually, please let me know.
New versions of the temple/fortress screenies; I've added the light effects to the map now. The entire room is just a bit darker than normal. The light effects on the window panes are static. The hint of yellow between the window and it's reflection is part of the overlay.
On this map, the lights flicker just a tad to simulate torch/candle light. (The torches also are on stepping to make the flames move).

@Luchino: I really like the map! it reminds me of phantasy star as well, just much prettier. The only thing that really stands out to me is that the light source on the buildings is the opposite side from the orbs on top of the buildings.
