Tirthankaras, the Gods of the Jain are therefore not the all powerful supreme beings of other religions  but rather living beings who have overcome their baser instincts to attain perfect knowledge, vision, power and bliss.   They then become teachers and role models for those who seek spiritual guidance. 

All living beings have the potential to become Gods of the Jain religion

Depictions of the Tirthankaras are always represented as seated with their legs crossed in front, the toes of one foot resting close upon the knee of the other, and the right hand lying over the left in the lap.

Only two are represented differently: Parsvanatha,  who has snake-hoods over him, and Suparsva, with a smaller group of snake-hoods.

If it isn't beautifully and intricately carved it can't be Jain.
