The delicate shades in this are beautiful. It must have taken a while to do. Please can you tell me which paper surface you are using - is it matt, semi-matt or gloss? Also, do you use special pencils? I would love to try something like this myself.
Edward- This was done on Ilford WTMG semi-mat. I usually use MGIV mat, but any mat fiber paper will work. Pencils are the easiest to start with. I use Marshall's, Prismacolor, Walnut Hollow, Crayola (any colored pencil works). It's not too hard, and fun to do.
