Hi WoT,
Very nice start to what will hopefully be a much larger castle!
I, too, like your work on having a hall, chambers and kitchen -- no castle was ever without these. Indeed, most medieval knights and aristocrats never had the resources to build their own castles, but no self-respecting medieval lord would have been without a hall (for feasting, conducting 'public' business and dispensing justice) and a chamber (for more private conversations and sleeping).
Good luck in the hunt for more Steck, so you can keep expanding!
Cheers,
AndrewL
