As much as I've always liked your oriental style I've always thought it lacked enough character overall to distinguish itself from normal tf2 themes... right now it's just a small step away from typical metal/wood because of the surroundings. The architecture is PHENOMENAL as always, but the map needs to elevate itself by using oriental themes in the layout and design. Perhaps, as I suggested when we tested some the other day, you could take the theme a step further:

This map is one of my favorite examples of a mapper nailing the theme. Granted, it's supposed to be jungly-ruins, but I think you get what I'm hinting at. Those cut-outs that are used on that map are AMAZING. I don't know if you could get something similar or come up with an alternative, but you should go nuts with the oriental theme. Think about the map monkey from fortress forever (yes a different universe, BUT...)

It really goes to town with the oriental touches. I especially love the cliche "zen" feel the middle area of the map invokes. Any tf2 oriental map should just be dripping with bamboo and wooden bridges over meditation pools! :3

This is concept art from the bond movie Dr. No, which has a strong oriental theme. I LOVE the architecture, it would fit perfectly as an interior to any spytech spaces you have.
And then, most obscurely of all, there was this AMAZING tfc map called kyoto. I know it was flag push and it had the most brilliant layout... and I can't find it now!
I'll dig around some, but if you know anyone who actively plays tfc they may have it downloaded from once upon a time.
