Chances are you need to turn up the settings for the indirect lighting in the render room. There are several switches that you can flip to change the results but I would start by setting the quality higher than the default and also decreasing the pixel accuracy. You will have to pay for it in render time but you can get the results to be a lot better than what you have here. You can find the settings I'm describing when you click on the icon at the top which takes you to the room where you render the final images (icon all the way to the right up where the wrench, film strip, paint brush etc are). There will be a tray (panel) on the right which will have the render settings in it. -Kix
