Looking forward how this progresses.
A first impression is that it all looks somewhat too clean and sterile.
All wooden beams of the house and the planks of the fence look too straight and sharp.
I like the moss on the roof, but would expect the chimney, wooden beams, etc ... to also be somewhat dirty. Same for the fence and mailbox.
Also the lighting seems a little off.
As there is quite a distinctive shadow of the tree on the house, one would expect it's quite a sunny day. Yet the lighting, an especially the shadowy area in the background is quite dark.
Easy talking, I know.
I am facing the same issues when it comes to lighting ... I know it doesn't feel right, but have yet to come up with a good way to fix it.
Good luck with the short.
