Looking good! The wicker basket is quite nice, gimme wireframes please. :3 Increasing the high samples will help on objects directly being hit by the light, high sample limit is the number of reflective/refractive bounces the light will do before it stops using the high sample value and use the low sample value instead for the sake of performance. It's the reason why smoothly shaded objects might look noisy in a mirror with a high sample of 64, high sample limit of 1 and a low sample of 1. Looks like the high samples need a boost and I'd suggest balancing it out with the anti aliasing. Also try reducing the number of area lights, if one light can cover a few windows then might want to give that a shot.

P.S xGen is a PITA >.>
