*shudders at plant* Hey anything's possible!
The curtains are off because of the "attempted" hemming at the bottom - and yeah you're right - those chairs do clutter the scene. As for the FOV, anything higher It would look very skewed, anything lower and you can just about only see the Television without actually moving the camera- and in this scene, the camera is right against the wall, so any further and you'd see nothing lol!
hmm.. As for colour, I would have no idea which other colours to use - I ended up giving the walls a very very light tint of green so it gives a different shade when the skylight/direct light bounces off it - probably not visible though.
I've managed to get rid of those Artifacts (BTW I forgot that I fixed them up in PS in my first render, so really, you cant see the artifacts I was talking about in the first render
Cheers, Greg.
