Spellbook Guardians

Apparently I am working with a friend of mine and he is trying to release a card game. Him and his friends are the employees and he recently hired me to work on the artworks. I don't really know what the final name of the game is...Well he did say it is 'Zenscroll' .

This is one of them. These are supposed to be four guardians of a spellbook that the player receives after completing a set of tasks. He hasn't told me the full story yet but I remember this is all he told me so far.

The HD Versions of these , except the green lady, is available on my Deviantart as well : https://michaelparkerkp.deviantart.com/gallery/
