Cagliostro Clock Tower and Castle Ruins

I've been working on a rough version of the clock tower from the Castle of Cagliostro and it's surroundings. It's not perfect but it's close to what I'd like. One face has a working clock that you can switch on at the bottom, I've tried to imitate the constantly moving innards of the tower with redstone and there are a few other things I hope you'll recognise. I just thought I'd share it in case anyone would like a little slice of Cagliostro to wander round in.

If anyone has any suggestions as to what would make it better, or whether I'm just wasting my time, please say so (or mess around with it yourself), it's meant to be part of a bigger project for if/when I have the motivation.

Enjoy!
