I made this last year (2002). When I did this I shaded it using an improvised "tortillion" (I forgot the term or the spelling @_@) but its the paper rolled into the shape of a pencil. It makes your shadings more controlled. I was quite satisfed with my work until I noticed that their necks are too long! T_T A friend of mine even joked, "Pammy baka naman na inspire ka ng giraffe."
