I played more with the final image, Got into the area lights propreteis and set the U and V samples higher, as well I strech the area light to get softer shadow like inside an interior
I'm very happy with XSI, It's much more fun, adv. and good looking then LW.
at first I was not sure about swiching from LW to XSI but now Im much more then sure that it was a very right decision.
Mental ray shader is far more flexible then LW shading system, and It's preduce better results on reflections, the control you have in XSI is so much better and fill right to use.
Next project will be to render the skyline I made along time ago .
so again thanks all and here is the image:
