I took the photo from my phone as the actual artwork is still at school but this is what I've done so far for my Visual Arts HSC!
It's done with an inkwash for the background and red ink dribblings for the abstract tree. I've drawn the figure using black and white pens (and let me tell you, it's annoying to attempt to tone figures with pen!)
This is actually an older photo of it, as I've done a heap more for it recently~
I've only done 2/7 of mine [link]
Yours looks really cool
