What medium is the work of art above? What do you notice about the artwork with regards to color and value?

Aa i believe is the answer to your question

Generally spontaneous human combustion is something that still bewilders some, human combustion happens very rarely and doesn't affect the surrounding areas, so unless you want to set your self on fire, human combustion will remain spontaneous and very rare.

If you could give us the questions i can see if i can you! : )
