another step forward ..

I followed the advice of Johny and I have given more power and color
I study, I try, I suffer

Yes this is good way!
Watch around Yourself: Tv screen is darker, ceramic have fresnel, plastic Tv have better reflection with small blurr, floor need better quality: wood texture with incidental angle alpha+greyscale texture wood (becouse floor not ideal relfect enviroment and never have ideal reflection), glass table need deep green colour and strong reflection on 90 angle, forget specular too, glass on pictures need stronger reflection.
please render big scale with FSAA G3 BOX 0.8 and after that rescale under PS to 50% of size with Bicubic Sharper.

good!

And fix the material of the curtain... maybe a little fabric texture.

Looks good to me, but in addition to comments, i would add refraction to table's glass and looks like there are smoothing problems on metalic surfaces like drawer handles and table frame. Reflections look weird. Try to reduce smoothing angle, if it won't help you can try to break geometry apart. Like cut/paste ends of handle bars.

it is true. I noticed too, in making up, that the smoothing is too high in metals.
For the floor, I have only one texture arroway low resolution .. I do not think you can improve.
thanks for your comments
