Excellent piece of art, I love the way you used the white pencil to make the highlights! It's a white pencil, right? If so, what kind of paper are you using? I'd love to do the same kind of thing (Shading wise) to my drawings!
Thank you C: And yes, it's a white charcoal paper. The paper I use is from my Toned Strathmore Sketchbook. Which can be found here [link]
I find having toned paper help to get such stronger contrast compared to white paper. It's MUCH easier to get the highlights xD And it manages to tone down the darks just enough to make sure they're not offensive. OTL, I hope that makes sense.
