What is the significance of Reclining Buddha Statue in Laos compared to other countries in Asia?
This is a depiction of the Buddha in his last moments of life, just before he achieved parinibbana (nirvana-after-death). There are 32 signs of a great man and 80 secondary signs (all of which the Buddha possessed) https://en.wikipedia.org/wiki/Physical_characteristics_of_the_Buddha#The_32_Signs_of_a_Great_Man and long slender fingers, long earlobes as depicted are two of the lesser signs.. I guess if you examine it up close, you will probably get some more  (foot arches etc?)! As for the differences, I am not well versed in art or its history, sorry!
