I have learned the hard way that styrene walls, to which DAS has been applied with PVA, warp alarmingly without bracing and even then that it doesn't mater how much bracing I use, the styrene will still find a way to warp in some unpredictable way. I have also learned that DAS is forgiving and will happily bend back into shape without cracking provided the warping is not too bad. Wonderful stuff.
For the first time I have used, mostly, windows from Truetexture which are quite expensive but very good. Worth it.
Lots still to do, which suits me just fine. This is another model I don't want to finish. Blogging about it puts off that day!
