A slightly different angle could be good. Secondly I would put some kind of background ( a bit neutral ) behind it. Check some of the image here to get an idea what I do mean, http://hivewire3d.com/forum/showthread.php?125-The-I-just-wanted-to-post-an-image-thread!/page21

Also some hints on the pose.... my oldest daughter was a ballet-dancer, now that she has a little girl, she stopped dancing, so I've seen her dancing many many times. The legs are fine. The upper body is tilted too much backwards, it needs to be straight. The arm pointing backwards needs to be in line with the legs as well and I would put the arm pointing to the front a bit higher. Best thing to with ballet poses, is look up the pose and try to mimic it as best as you can, so in this case, look up Grand Jeté and check the position of the feet as well.

Perhaps also let her look into the camera so that she looks at and interacts more with the audience, in this case potential customers :)

By the way keep the reflective floor :) Even though you're not selling the floor, it does support the character..... a lot!
