What a wonderful castle. At first I was inclined to comment on the amount of activity (as a lot of castle builders on here tend to stockpile their castles with minifigs and animals and stuff), but having visited quite a few of these castles myself, I think this gives a more realistic view of what most castles look like inside (at least nowadays). Keep 'em coming!
It's really fantastic... There are nice details and colours are ok. There is a big wall but i think you need to give some people here. It will look much better. But without the people it looks fantastic too. You have a great imagination. I'm waiting for your next castles! :D
