I think I'm going in the right direction with this image.
Rendered the image out with passes although I still haven't used the Mila material. I've got a diffuse, indirect, reflection and refraction pass. When combining them in Photoshop they reproduce the beauty image perfectly. The only problem I've had with this is that Photoshop somehow doesn't let me edit the 32 bit image. I can't create adjustment layers or use masks. So the above image is just the beauty render with a lot of adjustment layers and masks...edited in 16 bit.
I do have the non comercial version of Nuke installed so I'll give it a shot with Nuke somewere in the next few days.

Few things that I'm not happy with at the moment are the textures for the window frames and the wall behind the piece of furniture. Also not that happy with the LED light above the mirror.

Other than that I'm pretty happy with this image.
