Thank you for you comments glimpse , I agree a lot! I actually posted it by mistake here

It was meant to go to the WIP gallery.
-I did some tests on sun+sky(white color) lighting, that's why it's so overexposed in the area near the window. The good is that there is a lot of light in the room and the image cleaned pretty fast. coherent is very fast, I love it
-The "seam" problem happens because the texture isn't tiled and the edge is in a very visible place

-furniture is a bit stuffed as I wanted to use some new models, but its also very close to how the room looks in real
-dof is not used on purpose. I liked the chair detail and I don't use a photographic approach a lot on the renders
-you mentioned some geometry issues? where do you think is the mistake? I'd like to do some corrections
