This is my quick method to paint up a unit of Pink Horrors, I start out by testing on a single model and then paint in batches of 3.  Once the Shade, Base, Shade stage is dry you can whip through each model in 20 mins.
  
The Horror 
- Undercoat the model in   Corax White  or   Wraithbone  , for me I grabbed the nearest rattle can and have 6 in Corax White and 4 in Wraithbone.
 - Rather than follow the method from GW, I did an initial shade with   Carroburg Crimson  , followed by a heavy drybrush of   Pink Horror  with a second shade of   Carroburg Crimson .  This gave more definition to the muscle structure on the Horror.
 - I then thinned   Emperor's Children  with water and started to layer this up over the whole model, adding   White Scar  to the mix towards the end.
 - The tongue was basecoated with   Daemonette Hide , given a wash with   Druchii Violet  and a highlight with   Celestra Grey .
 - The eyes, teeth, nails and talons were basecoated with   Celestra Grey  with a highlight of   White Scar  
 - Bangles, Rings and Braclets were basecoated with   Balthasar Gold  , give a wash with   Reikland Fleshshade  layered up with   Auric Armour Gold  and finally   Stormhost Silver  
 
Finally the base is   Steel Legion Drab , PVA glue and your preferred basing material. There is also a small magnet superglued to the underside of the base for transport.  Duncan Rhodes has a great video on making cases here https://youtu.be/eKg8oPF4xfk.
