As a rookie author myself i hope your novel does well and you enjoy writing. All the best on the trails ahead.
As a reader, I found the premise of your story to be very intriguing, especially with the heavenly tribulation origins. The world has potential for intrigue and grabbing someone's attention. I appreciate the creativity.
As for the con, the conversations between the characters are not organic, making it feel unreal and stiff. Also, the transition between the different scenes seemed a little rushed.
In my eyes, your novel has potential as long as you work on the interactions and the pacing. Those are my humble two cents as a reader. All the best!!!
