How can I improve my image?

[Sonneur]

Hello to all.

First, I am French and my English is very bad, I translate it with Google.

I work for a home builder. I just start with Vray for SU.
It's very difficult to have help for VRay in french.

Here's the kind of image that we have made with SU

and now the sort of images we would like to have :


For the moment I can not. I have trouble with sun, light, shadows...
Here is my version SU 6.

Re: How can I improve my image?

Re-hello.

When I said "image" I wanted to said "render".

This is the kind of render that I have for the moment (the textures are not on the image). How to get stronger shadows like on the 2 examples above ? And why it is so blue ?
