Cool worm!

I think you correctly established a vanishing point and made some of the lines converge there. But then instead of having all of the lines converge you made them parallel to the lines near them. I have added a picture to highlight two examples of it. All of those lines should converge to the same point for the illusion of a 3D space to work. At the moment the objects at the back of the kitchen don't look smaller than the objects closer to the viewer because the lines are not converging.

Could you tell me pls who is the author? Thx
