Face Charts...

'Before' Child: I would do very simple base make-up as she is meant to be around the age of 10-14, lots of blush so show innocence, youth and to create a flushed dewy look. I would add slight bags under the eyes as lots of children often look tired especially if they are up early for a school photograph. I would use minimal mascara to make the eyes look bigger and brighter. The lips i would add a slight red tone to just to make the model look extra feminine and girly.

 'After' Child: I would start off with the same base make-up as before but then layer the rest on. I would make the bags under the eyes bigger and darker as she was incredibly tired and now dead, I would also make them look a little red and sore. I would make the lips look sore and slightly bitten. To show she has been beaten to death in her sleep, I would give her a bloody head injury where all the blood has congealed  dried and matted in her hair and trickled down her face. I would also give her a slightly bloody nose and mouth that has also gone tacky.
