Reducing the Amount of Characters

At the moment I have eight archetypal characters which for the purposes of this project is too much. I need to reduce this number so I can focus more on the important elements and quality instead of quantity.

Luckily some of my character archetypes are relatively similar, therefore I can reduce the number by selecting one out of each type. Below is each pair of archetypes and the similarities that they share.

• Maiden vs. Child - Both generally innocent, vulnerable characters. Favoured by the audience.
• Trickster vs. Shapeshifter - Devious, cunning. Both have a selfish agenda and only care about themselves. Can be good or evil.
• Astronomer vs. Wise Old Man - Knowledgeable characters. Someone to go to for advice.  

I have narrowed my character list down to the following five;

1. Mother Nature
2. Maiden
3. The Hunter
4. Trickster
5. Wise Old Man
