This is my idea for the castle wall i don't take credits for it but i have never seen it yet, so if someone knows any MOC with this scheme please let me know :)
About this creation
I made this in LDD (LEGO digital designer). Thing is that i didn't randomise'd it all i copied some of the sections so it may look a little sloppy. The thing is i used snot to create different depth and heihgt of the tiles.
