Castle updates and Audio Production Q&A

Well, I worked on my castle more today. I fixed the problems with the textures on the back (I forgot to get a screen shot of the problem so I can't show you what was going on). I also added a stained glass window and two wooden doors. I may put small windows on the towers, not sure yet.
Oh, and I apologize now for the not-so-dynamic screen shot. Where the water and sky meet in the pic are bothering me but the only other picture I have of the new features on the castle lacks the door on the side. It has a better vantage point, but I'm trying to show what I've accomplished... so here she be:
