Looks good.
If I were to detail nitpick the roof texture looks odd as
a) it appears to be orientated wrong by 90 degrees in places (front face)
b) you have nothing to hold the stones in place - it would need something solid undernearth it like timber or steel panels or precast concrete section.
Looks like you're missing a couple of supports at the bottom right as per
this image I guess you might not have completed the supports though by your comment.
Supports could definitely do with some
flanges as well to improve the realism.
The trees look really fantastic though, the whole scene looks like its coming together well!
