Very nice renderings, I do wish I caould make them myself!
My comments would be:
-in the top view I'd hide the celiling fan, it looks out of place for me, like something on the coffe table
- the view of the living room: the outside is way too bright and strong, it dominates over the interior. Same with the tv - sports also doesn't seem to go with the tranquility the room conveys. The reflections on the secutity glass of the fireplace kill the fire, I'd bet it'd look much better if the fire was the focal point instead of the tv.
- The iMac material isn't grainy at all, it's just brushed aluminium. (could be the result of making the picture smaller, but that's what popped out). Also the startup screen clashes with the overall colour scheme you use.
-the plants are a bit too neon green for my taste, they almost look like plastic


These are just cosmetics, but they would probaly make the renders stand out even more. Good work overall!
