[Feedback] Too much detail?

Hello! I wasn't sure where else to post, so I'm glad I found this. I'm fourteen and I wrote my first novel two years ago. I now want to get it published. So I'm getting feedback from some of my friends (who are all 14-17 so they're not the best editors, but I'm poor so I don't get a professional). I was wondering where to post so I could get some feedback from people who are editors. I was hoping I could put an example of some paragraphs from my story but I'm not sure how to. I'm not very good with computers so if someone can help me with that, I'd really appreciate it. Thanks!<br><br><br><br><br>Edit: <br>I should probably mention that this is fantasy so it's probably a bit different from realistic fiction.
