Hi stuh505!
Thkx man.
Dont worry, these are just the 3d stills and a WIP so im changing things hopefully if i have time.
.
When the animation comes if it comes, every material will be changed. To faster, hopefully.
Also resolution will be much much less than this images and ill try ofc to do the best i can do and learn with it.
This is a work for me first of all. 3D Portfolio. A work for practice - skills etc.
The client will have this for free.
Im giving it just for the pleasure of doing 3d and try doing something nice with architecture, and visualization.
I just hope the house finishes well. For the sake of the client.
Ive heard his wishes and we are trying to make it real, but unfortunatly some people around here (portugal) dont understand architecture, and its very hard to convince whats best for the local region and himself.
About the dirt, the house is still missing the stone walls - local region material - in some important parts to prevent infiltrations. Its also missing the tiles of roof - local region material too - which will follow soon. Im allways into adding dirt, i like it. 
Im posting some plaster test imgs with a bit of color tone.
Lets discuss the 3D and not the client issues, in my honest opinion.

Cheers,
