Overall, I was surprised at how well detailed it all was. It really does feel like a real place in so far as it really resembled a real place. I know it is your house, but I just want to say even though I've never been there, I think I have a pretty good idea.

Also, what really impressed me was the 3D skybox. the way you managed to slip the displacements between them, seemed really well done. and the skybox trees are the right distance away. as well as the skybox building models. And with minimal content, you pulled off a nice scene.

A few little things like the water could probably be scaled up a bit so it's animation didn't seem so apparent. And the map didn't seem to have any cubemaps built yet. All I saw were what looked like skybox reflections. I ran "buildcubemaps" and only loaded 3 of them (as far as I could tell).

Overall though, I don't know how well it will play as a DM map, but as an accurate representation of a real place, it looks believable. And I can't believe this map took 20 hours to compile, that's crazy. There are some complicated brushwork for the angles in the house, and I must imagine, vis had a fun time dealing with that. A map of this size should not take 20 hours to compile. But whatever you did, it seems to have come out nicely. A shame you can't work on it further.
