My daughter (a sixth form student - you know the ones that spend most of their free time at home horizontal on the bed or sliding to the sofa for more horizontal time) is studying Art at A-level, also History and Spanish, and she wants to pursue a career in special effects make up etc & already has a plan for which University she will be attending to get her degree.
Before she goes off on her adventures I have asked her to sketch my characters for the first book based solely on my descriptions. Of course, the reader will have their own image of what Allandrea, Eli and Fishbone etc. look like, but I plan to have sketches of the individuals for your viewing pleasure.
I will get her to sign the sketches, because when she's the top make up artist on a feature film, they could be worth a fortune.
