That statue puzzle is what you need to do to advance.
Here are some small hints that may help. Not each statue need sto look in a different direction. There is a fifth not interactable statue to take into account as well.
Hope this helps. If not fell free to ask again^^
I also have included the solution if you do like the answer. It's below in this post.
Dragon 1: North (This is the mighty dragon. He likes people who are strong and honest.)
Dragon 2: South (This is the cowardly dragon. He is afraid of other dragons.)
Dragon 3: East (This is the heroic dragon. He faces evil and protect the weak.)
Dragon 4: South (This is the evil dragon. He plays dirty and likes to bully weaklings.)
