The steam is obscuring the spot where the front right stool leg intersects visually with the brazier rim so it makes it seem like the front right leg is closer to the viewer than it is.





Yup, if you pay attention to the light and shadows on the chair legs it breaks that illusion.
I do think it’s that smoke that allows us to see the chair legs as going into the brazier, instead of being well behind it.
