That's the best looking lousey shack EVER!
Good job. Very faithful to the Morrowind shack. We just need textures to awesomeify it. Unfortunately, this is the kind of texture I can't make. My talents are more towards making variations of dirt. :-D
EDIT: I imported it into 3DS Max. It's kinda inefficient... I was able to bring the vertice count down from 1602 to 513... It might have been nifskope that did that. I kinda doubt it though. I noticed you didn't weld anything.
Your roof had 119 polygons in it... I shrunk it to 17. But I had to redo the whole thing, something was preventing the vertices from welding properly and I'm blaming Nifskope.
I redid most of it using polygons and welding, exported it, and reimported it. I have not the slightest clue what this did to your texturing job (As I didn't elect to import the textures from my Morrowind folder), but it got the vertice count down to 429. I also added a 32 vertice collision mesh for you, and I applied radiosity vertice shading.
Download it if you wish.
In any case, this was a really good mesh. Just needed some cleanup, and you will notice all of my vertices are in the same place as yours. You did a swell job putting them in place (And I'd assume putting textures on them, which is hard), so don't think I'm faulting you there. You have good artistic talents, you just need to expound upon optimizing your stuff.
Edit again: I noticed you wanted a size comparison. Well, I'm not putting that into TES4 yet, as I don't have the textures set up or anything. However, here's a 100% scale-accurate Redoran House. This is a pretty big building, as a person is as tall as the door. Your shack, IMHO, is just a tad big. No big deal just resize it down a little. First, convert it to an editable mesh, then select all of the vertices, then scale them down. This will keep it from getting messed up in the export process, as shrinking a mesh without shrinking each vertice doesn't actually do anything ingame for some odd reason. :/ Scale pic attached.
