A new writer might ask:
Do I put too much violence in the story? Too much dialog? Not enough dialog?
Too much backstory?
The answer isn't the same for everyone.
You can simply try to write a second version changing whatever it is you're concerned about. Put the story aside for a while, and go back and review both versions.
Get several friends to read a section of your writing, and listen to the comments objectively and watch for similar opinions. If several people notice a problem, then likely it's not just a matter of taste.
Be honest with yourself.
