Alrighty, this one was pretty fun to do.
-The cover/banner: The cover is solid, the banner, though. It looks very odd when it's small. Nine's face looks very weird when small but is pretty good when I opened the info page. If I could, I would also say that the description lacks splendour. It needs to be more showy.
For example:
15 years ago, a fighting game was released called Ignis Somnia.
This is very passive and lacklustre. I would have instead gone with something along the lines of:
The world of gaming changed 15 years ago with the launch of Ignis Somnia.
More experienced writers could probably make it even more dramatic. The very first line that your readers will read needs to be as hooking as possible.
-How hooking the prologue is: This part is done very well. (I'll talk about the general artwork later) The Prologue is super dynamic, each panel is very showy and your amazing skill is well displayed. The dialogues are clear and the plot is snappily introduced. Very hooking.
Impressions on the first few chapters and whether they make me want to keep reading: What happened from chapter 4? It can be hard to keep maintaining the same quality for a long time but you should've given a heads up in the description? Keeping the change in art aside, the story is plenty intriguing and you are building it up well so it does make me want to continue reading but...
-General story and/or artwork: ...the art is inconsistent. Your angles and perspective is masterfully deployed. It is done beautifully and the different expressions on every character is conveyed beautifully. But the anatomy errors keep popping up here and there.
Like in these parts:
This panel is amazing
And this one too.
But what happened here? His whole body is all over the place.
-Style, tone, and setting: My complain here is fixed from chapter 3, I will just say it anyway since the first chapter could really use it. The backgrounds need more details. It's hard to make out what kind of world our story takes place in.
-Writing/storytelling style and how smooth it is: You've nailed this part. There was no place that I found it too fast paced nor any place where it was too slow paced. Getting to know more about Ignis Somnia before we got the tournament would have been a good thing, but it's fine this way too.
I really enjoyed reading it and I got to learn a bit for myself as well. It's a great read so far and I can't wait to read ahead!
