I've been playing this mod for a couple weeks now and I am completely in love. Every time I come to a new village or town, I take a lot of time exploring it on my horse. The scenes in this mod are incredibly high quality — there's a couple generic town/farm ones that I absolutely never get sick of galloping around in.
Once I discovered the fortified manor feature, I've been having a blast running around that huge map and seeing my town grow. I decided I wanted to make the area even more horse-exploring friendly, so I've been editing the euro_plains_fortifed_manor scene off and on to make it much more lush and have a lot more props. I added some new farmland, forests, rivers and a few hidden areas. There's lots of hills and trees to slalom through now if you enjoy rushing around on your horse as much as I do. If anyone would like a copy of my new scene file I'd be happy to share it, but I imagine it would only run well on a beefy computer because of the horrifyingly large amount of flora I've added. I don't notice any performance difference between this version and the original fortifed manor scene, but I have a good computer.
I didn't move or change any of the upgradable buildings, so it still works exactly the same as the original fortified manor, just with a new landscape and added props which appear when you purchase new segments of your manor.
Here are some screenshots:
