I'll focus less on the art side of things and more on the story and style for this one. I don't think I am qualified to call you out on anything art-related.
-The cover/banner: I like the cover. It has great visuals.
-How hooking the prologue is: Your art is pretty good, so many people will stay just for that. Some dialogues felt unnatural at places. Like Amelia's first thoughts after, what I assume is being drugged, and taken to hell, were how she looks like her younger self.
It would make more sense for her to be confused, she would probably notice the inner changes. Since she's old, it would be easier for her to breathe and move and she would probably notice these things before she could even sit up. I know that conveying these small things in comics can be difficult and time-consuming, but it would have greatly enhanced the vibe of your story.
I'll also say that it was difficult to follow the events of the first chapters at times, but that's probably just me.
-Impressions on the first few chapters and whether they make me want to keep reading: Yes. In fact, I caught up myself. There are a few grammar/spelling errors in between, but other than that, it's a great read.
-General story and/or artwork: It's still in its initial stages so saying anything about the story is not possible. I'll at least say that I am really liking how you are building it up. Slowly introducing the world and the characters while hinting at the main goal of the story. Great work there.
-Style, tone, and setting: Beautifully expressed. The visuals are great and the paneling is done very nicely. Nothing to criticize here.
-Writing/storytelling style and how smooth it is: Again, there are a few grammar/spelling errors and some places where the dialogues feel unnatural. Barring those, it flows very well and the story lures me in.
I really enjoyed reading it and can't wait to read more. Keep up the great work!
