Help with full body self portrait

I just started an indepence study for my art class and just started a project las Friday. I’m thinking of drawing myself unto a sheet of wood I got. It measures 8 foot by 4 foot. I already painted it white with acrylic paint. I’m thinking of doing the self full body portrait with graphite than going over it with colorsplash of graffiti. I need help since this is my first time drawing a self portrait (full body) “live size” unto a wood surface.
What are your recommendations?
Any cool ideato for me to add?
So far I want the background to stay white and my body beblack and white. By the way I’m a female 5’3″ is my height
