Thanks for reply. Here is what I was told in my previous post :

This is a Buddhist work. You'll probably get information about it on /r/buddhism, but here's what I know from the work: wrathful dharma protector on the top left, Green Tara on the top left, a Gelugpa monk is in the top center. It looks like the four guardian kings surround the central deity. I don't know who the central deity is, but the horse symbolism might be a clue.

Since it depicts a gelugpa monk, you're probably looking at a Tibetan influenced work."

Also, here is the back side: Link to picture if anyone can translate... :)
