We really like the way you're playing with the "L" and "D" to produce an icon.
At first glance, the logo feels a little "wimpy" and we need to convey a stronger message.
Of the four choices, we prefer #99 -- the LD works better when it's all one color, because otherwise it looks like half of a clock face.
What about moving the LD to the left of the name, making it stronger somehow, making "Luxious" larger, with "Design" underneath "Luxious"?
We're also interested in seeing some other sans-serif font options.
Finally, the logo will need to work well on a white or a black background (although a color change as appropriate is fine)... but if you show example backgrounds, please stick to white and black.
