I'm hesitant to comment on this series at all, on the chance that critique would get you second-guessing yourself, Lamb. After reading Lupin's comment, I also noticed something odd with the hearth and chimney. The angle is in line with the back wall of the home, which makes sense, and were it facing into the home, we'd not see the inside of the hearth. So, it makes sense logically, and looks really good by itself, but is conspicuously standing out, and I can't put my finger on why...
Also, I'm really enjoying how the mountains are coming together! On the far side of the gorge, it looks like moss and other hardy vegetation is beginning to appear on the craggy cliffside... awesome. The red flowers coming up the side of the farmhouse are a lovely touch, a nice splash of bright color drawing the eye to details of the crumbling walls and sagging roof.
The regularity of the updates & refinements is highly welcome. I look forward to them.
