Tutankhamon's Golden Mask - Right Eye and Eyebrows

Today I worked on the right eye and the eyebrows. The brows and the "eye liner" are made of pieces of lapis lazuli, carefully fitted together so at a glance they look like one piece in real life. I wanted to bring out this puzzle effect.

I use a miniature brush and was wondering why it did not give color well. I finally checked the brush and noticed it had only one hair left! And I must have painted with that for at least half an hour LOL :D
