Ok, so I'm extremely late to the party and I found out about this like yesterday. I started a low poly and I'm almost done with it. So pretty much I'm going to bust my ass on this one and see if I can make something happen. If it don't look good by the deadline then .....well I guess this will be good practice.

It's hard to read the wood, there is detail, but not enough large shapes. They need accented edges too, those will help push the corners, helping the shape.
On the first two pictures of your most recent post, the roof shingles run together horizontally, that last one doesn't so much, not sure if it's normals or not, try painting in a little more AO.
Definitely a good base start. The roof has a good splattered grunge to it, it breaks up any patterns, definitely keep pushing this.
For a house set in this era, it's okay to be "sloppy" with vertexes, it adds to the character. A subtle touch of irregularity adds to the elements of nature and the forces thereof.
