This is very good work poser work! The best I've seen in a long time. The color textures are grand, and the color hues on the paneling in the background are great too. Theres a real sense of environment here, and the characters are well detailed too!
My only beef- Leia's chest area is too wide, and her breasts are too low, making it look like she has none and the bra was just placed on top of her. I understand this is a poser issue though, since poser tends to be very angular and robotic with poses and such.
There are other little things, but they aren't important.
