Remove Harmful Pictures From The School Art Curriculum e.g Skulls

Background

I want them to remove harmful content from the art curriculum and for the children to draw normal stuff e.g nature

Additional details

Some children especially sensitive ones can tense up to the sight of harmful content and it could cause children not going to their lessons. My son Nathan feels traumatised and does not like the curriculum as he has to constantly draw skulls which could damage his mental health.
