These people have to be either looking for something, or their figurines. It could be that the people are hunting the snail to eat for food. I’m pretty sure it is fake and it’s a drawing, the drawing is made by a good artist. What do you think it is? It definitely looks like a drawing I mean look at the leaf! What would you do if you could draw like that? Maybe draw a battle?, a drawing of your favorite scene from a game?, I know I would! But I’m not you so you would pick whatever you want.
