Thanks!
All done with a brush. Karell 3/0 synthetic round. I didn't sketch jasper first, but I did plot Agate. I'm using Sakura Koi 26 color travel set with warm water.

Agate's iris is very dark, almost the same color as the pupil in shadow. Keep the eye color dark and where the light catches the iris, give it a little color. Very very dark auburn. A highlight of orange instead of white. Keep highlights around the eyes to a minimum so the white reflection on the eye draw the viewer to it.
Part of what made this a bit more challenging is the lack of a visible eye on jasper. where is it? it's in there... somewhere.. in one of those darker strokes. Lol. without agate there, would anyone know I can paint eyes? /hmm
