Architectural Visulization

A house I’m working on

And A larger scene

Any recommendations would be great! Any tips on working with fairly large .blend files or tips on how to decrease the size of the file. I’ve tried grouping objects by material attributes but am still fordging on with a 40mb plus file.

Thanks a bundle.

it looks very good.
But i think that the texture a bit to much like pictures.
the modeling looks good.

the door could be just a bit more on the right. right in beween the stairs.
