New to YA fantasy

I don’t think I’ve ever attempted a YA fantasy before. I’ve don’t a bit of YA and a bit a fantasy. But it wasn’t until last month that I had the idea that combined the two of them. I ran with it and after like twenty chapters am I googling the questions ‘What are the elements of YA fantasy.’

Well, I came across an article that that gives some really good points and I think my story fits in pretty well 🙂 Maybe I need to work on the world building just a tad more because I’m not sure what technology I’m going to include. I’m not sure if I should add computers or the internet yet. This world has TV and newspapers as well as wall phones. Where do I draw the line with what to include and not? As the creator, I can do whatever I like, but readers are going to pick it apart so that I need to have a good reason as to why things are there and not.

Also for a young adult fantasy, I have a lot of adult characters. One half of the storyline are adult characters while the other half is not. The story cannot be what it is without both sides so I’m going to continue with them.
