Definately looking good
There are a few things which you could improve on; the rocks are very high key and quite globular, the roof doesn't overlap the walls and the left facing side (of the roof) could do with lightening up, the top of the windows is missing a visible ledge and perhaps the door a frame and the latest foliage pallete is very saturated, especially the lightest shade.
Some consistancy issues; the buildings cast shadow right whereas the trees cast straight down and the rocks, chimney and architectural details don't seem to cast any. Every tile on the roof is outlined whereas most everything else is treated with localised detail.
I made a (very) messy architectural paint-over. Also, I didn't edit this but you have tiles on a flat roof which I don't think would work realistically.
Thanks Jams, I must stress that I wouldn't put any of my rough edits in a game without cleaning them up a bit first
