It is an amazing castle. I could only echo previous comments. I love how it and the surroundings fit together so well, the castle really looks like it was built into/onto the rock and ground about it.
I'd leave the water stud up but perhaps some waves or greenery in it.
wow! How on earth did you get the walls at an angle to the grid? terrific MOC (not sure on the ninjas...) -T.R.
He who thinks you should look at the box that says "Quaraga" if you want to find out his username (about as useful to you as his real name). he only wants you to look so he can laugh about you looking there because he's a total smart...
This construct is awe-inspiring! Congrats and kudos to a phenomenal job well done. I can only fathom having the means to create such a large-scale model. I'm especially excited by the subtle accuracy of the waterfront dungeon escape/back door. Very very strong structural design.
