Hey Riven Fall, it looks like you've used one of my files from my Player and Party Underwear mod. The PFBLAD01.tga (dancer skin) that you supplied with this mod is actually based on my file, not the original TSL file. Please remove it, and re-do it (it's always important to keep track and use the original TSL file).
Also, when taking screen shots, it is always better to not have any other mods visible (to avoid confusion). In your screen shot, you show one of my dark side underwear skins, and some people might download your mod expecting to get my underwear.
As for your work, the head looks ok. You might want to fix the iris of her eyes, so that it is in the same place on each Dark Side transition (right now, it shifts around too much).
