Sequoyah has his ears and his fingers fully intact on that picture, his ears are just under his turban.
That portrait was made before 1837 so it would be Industrial Era. The Cherokee were nicknamed "The White Indians" because they adopted Western and Caucasian ways of life and dress. Only a few Cherokee's wore turbans and Sequoyah is believed to have done so. I myself have a turban very similar to Sequoyah's although I barely ever ware it (my spiked mohawk gets in the way
).
This is what I would do for each era:
Ancient - Sequoyah only wearing loin cloth, background are hills or other terrain like that of Georgia, Tennessee, and Carolinas.
Medieval - Sequoyah with more clothes, similar background.
Industrial - Sequoyah wearing what he's wearing in the portrait, background a cabin or something.
Modern - Sequoyah wearing a turban or not, in tuxedo or something. In front of Tahlequah, OK city hall.
