These 3 pages are from chapter 6. After a devastating end to chapter 5, Dante is overcome by anger. The darkness in him shuns away any hope remaining. In the final page, the borders go black; one, to show that we're moving into a night scene. Two, to signify the change in Dante's heart. The remaining 122 pages will have a black border until the finale.
Update
You all have been asking me for a color tutorial, so I've decided to make a video in it. My 120GB MacBook is over 8 years old and it's too low on space for updates and editing software. So I'm currently setting up a PC I built with my girlfriend to use for film making. I promise, promise, promise I'll have a video out for you all. I appreciate you all π
