Awesome! Your first castle MOC, eh? That's definitely 1290x better than my first castle MOC (which was also based on the Muiderslot) Here it is if you're interested... link.
This really is a great creation, both the castle itself and the terrain!
Your creation has already been spotted discussed on our Lowlug forum here
And lastly, welcome to Classic-Castle, it's always good to have another Dutchman around. You should tell us a little more, and introduce yourself over in the Announcements forum, if you want.
