Amazing renders!
I like a lot the close shots. Really great lighting and DOF playing. The wide views are nice too, but at the first one I found a light incongruence at back desk shelves. Maybe it's the distance or indirect lighting vray specs... I have my eyes fitted to unbiased renders.
Anyway, marvelous renders, and great interior design, taste to set all the furniture and modeling capabilities.

Thanks all for all the knowledges and things I got here.
