Colored Pencil on Blue Toned Paper (Patreon)

I made a rubbing on some textured glass. I used a white colored pencil for the rubbing. Usually when I do this, the rubbing texture becomes the darker values because I use a black pencil. so the texture recedes when I start rendering. This is the opposite, the texture becomes the the lighter value. The paper is already at a middle value. then I add the shadows in. 

It's hard to describe in text. 

I've been enjoying the feeling of Prismacolor pencils on this blue toned paper. There's something satisfying about the way colored pencils feel on paper. Plus there's not brushes to wash or paint to wipe up when I'm done.

When I scan it, I'm having a hard time getting the color to reflect what it really looks like.
