Beautiful! I always love drawings on tinted paper, it really makes the drawing pops out a lot, especially using white chalk or white colored pencils. You did a wonderful job with values! How are prismacolor pencils like? Do you like them and recommend them? I am thinking about buying a small set, right for grey tinted paper, instead of using common graphite pencils.
Thank you. And I agree on the tinted stock - it's brings a whole new dimension to a piece while "doing some of the work." You'll enjoy using Prismacolor pencils, or any good, soft, vibrant drawing pencil, on colored stock. Since you can use different pencils to change the values/colors, it's actually easier to achieve an effect than if using graphite - which I find really tough and requiring much more time, so kudos for doing that! Happy drawing - I think you'll enjoy Prismacolors. (And if you find a gray set, go for it, but I recommend buying individual pencils if you can't find a set you like. Brick and mortar as well as online stores usually sell them for about $1.25 each.)
