This is a portrait of my sister's daughter, I did her a photo last year, and I used that one as a reference for the pose.
I modeled without cloth simulations because I wanted the dress folds similar to the ones in the photo
but the intent in the end wasn't too realistic, just a portrait
I used Lightwave for modeling and Softimage for rendering, Photoshop for textures, then I did some little correction in Photoshop and I added a bit of glow.
