What's the pacing of your story?
Honestly, I don't know what the actually pacing is. Weirdly enough. Sometimes I think it's slow, and other times I think its fast. But I can never tell for my own work.
Is the structure mostly driven by plot or character arcs or is it heavily reliant on setting?
Plot and character. Most of the story, right now, revolve arround the MC learning to use to his new found powers, and why he has them. At the current stage the setting isn't really important -- because it's set in the real world -- but I like describing some of it so that people don't just read words on paper.
A story with lots of world-building will benefit more from description than one where the setting is easily understood.
This is the tricky part, for me, its not really world-building right now. It's mostly only about the powers in the story, as well as the MC's normal life. In the second part of the story, it's suppose to go to a different world -- where the actual story will take place -- And I'd have to describe everything there. But I'm not sure if I should start describing a lot now, so that people won't be blindsided by multiple paragraphs of just describing the location, clothes, and what not, later on.
