You are first on to picture her as powerfull witch.
Usually she is mean woman.. now she is powerfull and looking protective.
Reminds me about Granny Weatherwax, who also is older but not a hag..
A magnificent view of Louhi. You have managed to make her to look older and powerfull but not as a hag or crone, how witches are many times seen. Indeed she looks like a powerfull witch-queen of Pohjola.
As a Finn I am always pleased to find illustrations from our national epic. Thanks for the great picture.
