Aaand, it's done. Huzzah. During it's final stages a slight change of direction occured as it was suggested to me that I added a hint of 'some of those useless curtains that people have wrapped around poles at the top of their windows, but they don't do anything functional' (yes, that's how it was put to me). So now this painting which was originally thought of more as a 'sickly purple skinned person being helped up by bearded blue/greeny skinned person' has become more of a 'He snuck into her boudoir at night, guess what happened next...?' kind of painting. Thank you Richard.
Also, my new favourite thing... bioluminescence!
