Architectural upside down interior

[viralata]

This is a scene I started to test luxblend 2.5, but I gave up and came back to blender 2.49.
I wanted a interior render, because I don't have any yet, but I wanted to have more fun that just putting furniture, so it ended like that.
For the moment I used mostly furnitures from skopia blog, to set the scene and see the general layout, but I may change/modify them.

Nice idea Like it.

This wip staied untouched for a long time, but I continue it, in a quite different way: simpler, less objects, and maybe no upside down anymore, we'll see.
I still wanted something less usual than a kitchen rendering, so I started a mud house.

I want to keep a low contrast in colors, focusing on the indirect light mood, with only a few colorfull objects in the scene.
I use only one sun for the moment and may add lights inside later.
The big problem I have is as always rendering time. I wanted to try the hybrid bidir for this interior scene, but this noisy result is what I've got after a night of rendering (quad core q6600 and nvidia gtx470). The gpu load rise up to 35 % the first minute then decrease to 5% for the rest of the time. Any body with hints about the settings that could help ?

i like the new image a lot, the living form architectural style reminds a bit of gaudi

Keep it up i want to see it finished

The "flow of light" looks very good to me, nice mood

Very nice idea, this are good renders on a technical level and great surrealism.

The second render makes me think of places I have seen in New Mexico, it has a great sense of space.

Thanks for the comments. Here is an update. I solved my render times problems, seemed to be linked to my bumpmap problem: I can't have the bump map for the walls rendering correctly, so for the moment I just removed it. I still have to change the furnitures to make them fit more the image; add some details, improve the water.

Maybe a little underexposing of the burned out sunlight would be good? You coud just try to lower the sun gain so that the scene doesn't become too dark in general.
