This exercise was a challenge for me, as I have never really worked with Prismas on colored paper before. The hardest part, in my opinion, was making the depth of the curls in the paper believable. Paying close attention to where the shadows and really bright highlights were in the piece was crucial. I think the one on the bottom was my best work because I took the most care in observation for that one, along with placing the highlights exactly where I saw them. I loved blending the white and gray pencils, I think the gray midtones helped lessen the contrast between the paper and the white Prisma, which made the surface more realistic.
