My Livingr room problems

[ebad]

Hi every body!

I've made a new scenes and faced with a problem!

The attached image has some signs that helps me to say them.

First of all some shadows's missed and i really want to know why??

2nd:my gold material is a Ward (according to the vray materials)

Reflection color : RGB(211 , 137 , 27)

Refl.Glossines : 0.88

subdivs : 3 (I changed it to 10)

And all other is default.

Is there any usefull point for gold?

3rd:My Vray light mult is 14 (2 vray lights with mult:14) but i see in tutorials they set it arround 1 - 4 !!!??

4th : whats your mind about Using HDRI for GI Environment (Sky light).Here i 'v used HDRI for reflection/refraction etc environment only.

I'm waiting for comments.

Thanks.

one of the way i think put the shadow only in the direct light source.
