Thank you to all for the comments.
One question. Does this window only look good from one side?
Yes, this is the drawback of this technique. I didn't look for a better manner to avoid the white Technic 1x1 bricks. If someone find a better solution...
did you use the software to help out?
No. Just a good feeling with the bricks
I have to admit that my favorite part is "Jane Vig" peeking out from behind the wall holding the "3" tile. Very nice touch!
Thanks, it was to give life to the MOC, and what could be more expressive than a Castle Joe Vig holding a 3
to illustrate this 8x8 MOC ?
