I do like that Psycho - seems like a good start.
My only real concern is the same texture use up the wall. I can only question that maybe it is temp, since you still have a dev floor texture in there?
If not try to break it up a bit, maybe even consider adding some depth to the wall? A battlements that struts out supported by wooden beams off the side? Perhaps even an indented balcony on that second level?
I don't know, it just seems that it could be a little less flat and repetitive.
But like 2d said, good start and definitely has that traditional TFC feel to it. However I still think that you can expand on that style, not necessarily in a TF2 direction - but somewhere.
