Yes, there are jpeg reference images and line drawings to work from.
I'm a big fan of drawing, and if you have a good understanding of how drawing works, it can make the biggest jump forward in your paintings. But if you're super keen to get started with painting and engrossed in colour, then I've added a few downloads to help you out.
All of the images can be printed out A4 size allowing you to work 1:1 with your reference image (a classical technique called sight-size)
