Audience: To put it in marketing terms, all current and potential customers. What's their age, education level, culture/nationality...? For example, if you're writing a fan-fiction-esque story, obviously your intended audience loves the fiction piece you're basing your story on.
Purpose: Why are you writing this? Possible responses (but please don't word it like this in your RS!)
- Because you love the subject and have an interest in it
- Because you were interested to see how a story would turn out if you mixed certain concepts/explored several intersting ideas
- Because you feel passionate about this and want to share this with an audience
- Because you want to teach your audience something, or open their eyes to a new perspective of your concept
