From

this:


to this:



1. I cropped this picture to 100x100 and sharpened it



2. I screened the image once.



3. I used this gradient then set it so soft light



4. Then I used another gradient then set it to hard light, 56% opacity



5. I used this texture and set it to color dodge and erased some parts that hit her body



6. I added this light texture and set it to hue



There you go! Remember, tutorials are meant to guide, not to copy :)
