Nice job, Ruben. But I can see you had some problems with your masks. The blue is invading her hair in some areas and leaving out some skin spots. The mask is also invading her shirt. You should refine your selection using the Qualifier tool. If you do it with just masks, it will be almost impossible to control it in motion. I would also leave the blue out of the teeth and eyes. It would make the effect look a lot more natural.
Marc: the image is a TIFF file coming from a Nikon camera. Paulo: Thanks for the comments. The masks are not perfect, and for sure there is a need to refine the selection with the qualifyers. I will try these corrections and see if I can get it. Thanks a lot Regards
