Dragon Mural Concept

I've recently been doing installation murals around the city as a summer job. My first job was a large section of wall in a local Middle School--and this is my original concept for the mural. The PTSA for the school had originally approached me to create a fantasy mural, so I thought, "Sure. What's more over-the-top fantasy than dragons?" I thought the idea of having 8-foot-tall dragon heads on a wall sounded pretty cool. However, I live in a rather conservative town, for the most part, and once some of the student's parents heard about the proposed fantasy mural, they made a big fuss about it having religious or mystical content. I wound up painting a large mural of an underwater scene with dolphins and whatnot....which I'll post later. But I still think this is a cool concept. I tried to explain to them that each dragon is modeled after a particular cultural idea....from left to right: Germany, China, Japan, England, Mesopotamia. Some people just can't tolerate creativity.
