Really cool soundscape you created, it does remind me a lot of creepy temples at night, I've been to one haha.
I think one thing you could try is adjusting the overall mix a bit more, making certain sounds like some of the percussion and bells(?) a bit quieter might help make for an even more eerie vibe, since it is night time. Throwing in sudden louder sounds in the middle of that quieter mix might enhance the creepiness of your music even more.
