Finish a render

I need someone who can finish a render I started. I have the model in Rhino 5 with vray materials. The final render should meet the following requests: -Sphere camera with 2:1 ratio (6000x3000) -Choose a nice view where we can see all the inside and a bit of the window, I will upload this render as a Facebook 360 photo. -Add elements for making it look more realistic, please, avoid adding new furnitures unless the ones in the webpage i will provide. -Add a background image in the white window, something urban. -Any doubt with colors or materials ask me before rendering. I´m attaching a draft of the actual scene
