I’m a neophyte with respect to Hindu iconography–plus I read no Indian languages, so I may be wrong about this being a Shiva. Shiva is usually depicted clean-shaven, but I’ve seen bearded images. I mostly based my conclusion on the tiger skin (or stylized representation thereof) that he’s sitting on, which is often associated with Shiva.
Shiva is part of the Hindu trinity, which also includes Brahma (the creator) and Vishnu (the sustainer.) This leaves Shiva, the destroyer.
If you’re someone who actually knows about such things, and know I’m wrong, please drop me a comment to let me know.
