Thanks for your comments.

I made a mistake in the first post , the floor is a blin, not a mia material.

I dont really want to correct the picture, it looks nice to me, in fact the more realistic i have done till now, but thanks for the link that seems to be quite interesting and i may learn a lot.

Thats true, i like to use the sun and sky because by doing that you dont have to use hdr pictures and get very nice reflection effects.

thank you guys for your interest. I add another render i made with the same floor and lighting before putting the chairs.
