Here's a few progress shots of the 6mm castle. It is built in a pseudo-Gothic style. On the first photo, I have laid out the walls and the keep, and started adding a few details.
Everything is under a roof now, and still more details are being added. I hid the seams on the conical tower roofs. The irregular shape of the walls is a result of the marshy ground surrounding the castle. A gatehouse was also added.
Covering more empty space at the joints of the cardstock roof, and the base with sand. Later I put some GS bits at the bottom of the outcropping small towers - slowly but surely the thing is getting ready to be painted.
