My first major carving project is a 5 ft tall Dragon staff in Ash. (I never start small, silly me

)
My question is does anyone have any suggestions on how to carve Dragon eyes?
I have studiously researched Google images for "komodo dragons", reptiles, and dragons. I have several art books of paintings and drawings of dragons, these have been my best resource to date.
Does anyone have any other ideas?
Thanks to All in advance!
