Summarizing a few recent query responses to pass forward to other writers. Individual information will remain anonymous. Below are high level points from 5 submissions:

1. Rework the opening chapters and spend more time on the main character, use the environment/setting to show the main character’s reactions, feelings, etc. Show the event that startles her and her responses, and then have conflict and show how she chooses to handle the potentially hard situation.
2. The first three chapters are not the best place to start. Chapter 4 shows the main character much better and with a few things weaved in from earlier chapters, would be a much stronger opening chapter.
3. In chapter one, we don’t get the MC’s first name nor do we know what she looks like, what the college looks like, what country or city or state or town, what her life looks like around her. We don’t know much about where she is at, what time period or decade, what people are wearing and what’s in style, what foods they snack on, etc. We need more little details for the world-building and those can be small details added like a brand name jean jacket or backpack, or Air Jordans, etc. Does she have a laptop or use her phone to take notes or a notebook? 
4. Relook at the first chapters and where you’re building the environment and cities. Please consider show not tell as well as deep character profile to immerse the reader into the place and person’s life in the present day.
5. With four POVs, the main character is in and out in terms of scenes and chapters so we don’t attach to one character deep enough. One or two POVs can build two voices. The other POVs could be secondary characters.

As always, this business is very subjective. Views are my own. This blog post is intended to help provide some suggestions when editing first chapters.
