Sexy Mars WIP

I've put some colours on her today (thanks to my dear - she lent me more shades of red ^^), but I still need to make a background. I know I want to put her on a bed covered with rose petals, but I could use something more, to draw more details and not risk using up one marker to colour the background... Any ideas?
