RodGuen - There was something niggling me about the eyes, and you nailed it. I've made some slight adjustments to them, which I think have improved it (even though I don't know what "exorbited" means

)
Tangent Queen - Yeah, rough and simple - that's me

I've adjusted the eyes slightly following Rod's advice, and just generally continued to refine the body and dress some more.
In the background, as well as increasing the cooler colour, I've added some small areas of other colour, known as
discords. These are colours that are equidistant on a colour wheel from the dominant hue and each other and, if used sparingly, can add visual excitement. As the dominant colours are in the pink/purple/blue region, the discords in this case are orange/yellow and blue/green. I've kept them fairly subtle, so as not to overpower the rest of the picture.
