So far vvery well written, But I do suggest using other terms. I saw "spider-man" alot leaving less of an impact on me. May i suggest using another term like "webbed hero" or "Masked Bandet (sp)" The word choices were weak in some points of the example. Maybe looking up some more powerful or less systematic words will do that trick! I know this will be a great fan fiction to read! I will admit writing stories about things you don't know much about can be hard- but I know you can do this!
Yep! I get that a lot when it comes to "I'm not a fan of this, but it's their style." Reason I used the full name Nick Furry so many times. Instead of something else.
It really depends on where I'm writing. I like to write in first person, but I don't know the characters well enough. I like going with my own styles, but it's good to try something new.
