I'm not sure how you textured her body suit. It looks almost like you superimposed a flat pattern over the suit. Instead, put the cloth pattern on the texture map so the design will conform around the shape of the body. Also, if she's dancing, she needs to look like she's having more fun. Give her a smile, open her mouth like she's singing along with the music, do something with her face. She looks too serious for someone apprently having a good time. There's more than just a body pose involved. The face is also affected by the mood a person is in. Consider the entire figure, not just the position of the arms and legs. Melanie
