I'd call this an acquisition... Lol
I've just completed my 2nd major MOC build - my Castle Fort! A whole heap of bricks, mini-figs & Bricklink orders have gone into this - & I couldn't be happier with how it turned out
Being a massive fan of Lego Skeletons, I wanted to have them launching a sneak attack from behind (while Robin Hood & his partner in crime make off with the loot undetected...)
One thing I'll definitely learn from this is to plan how you're going to structure your base plates before you commence building - trying to plan the inner flooring after my Fort was completed was a pain in the ass...
