Architectural video render

I need a short video walkthrough of a villa at sunset.
The villa is already modelled:

(Please send me an email request if you cannot access the files.)
You only need to make the pool bigger and change the light tree so that it looks more gnarled, like a bonsai. Everything else can stay as it is for the moment.
I will send more detailed instructions but essentially the video starts with a view of the villa and grounds, including the pool, as the sun is setting. Then the scene becomes dark and the house, the pool, the tree, the rock waterfall and the garden are lit up.
It is important that all the elements look realistic so don't include things like people, which usually look cartoonish.
Please be specific in your bid and confirm that you understand what the work involves and that you have reviewed the source files.
