Anamorphic Chalk Painting for Halloween Party

Anamorphic Chalk Painting for Halloween Party: 1.6 m/ 4.4 meters. Excluding the break time, it took me more or less 8 hours working on my knees. I was still not done yet, but anyway here's the result. The thing that bothered me: they kept changing the lighting by the end the shading wasn't matching the lighting of the site.
