I've been getting my query for White Fire critiqued recently in Query Letter Hell. A lot of people have commented that it seems YA even though I don't mention character ages.

I can see where they're getting this from, but it's also a multiple point of view novel. My male main character is 18. My female main character is 16. But the other two viewpoint characters, who do not get mentioned in the query, are 25 and 30.

That's why I have trouble thinking of it as YA. Yes, most of the book focuses on the teenage characters, but I'm just not sure. I'm looking for some input. Is it YA or not? Personally, I don't think it is. I've read a lot of adult fantasy with one or more teenage character points of view.
