Ok just been searching the old internet for some more reference image to help towards the character design.
Seen these images of a middle eastern animation, with a simple shape for the character design.
I do want the crowd to have a uniformed looked with the same hair, sun glasses and similar clothes . Possible just changing the colour of the cloths to match their hear colour. Though the hair could look very similar in more than just shape.
I could keep the shape of the clothes all the same for each character. Only changing the colours and but not the design of the clothes. The colours would be different but the overall shape of the clothes would change.
The bottom two images are just ones that I liked when I was searching the old internet.
