Congrats on the release!
That's one killer banner. Awesome.
Your linework is pretty cool too. Clean. I like the character's expressions!
If you allow me just one pointer, in page two, seconds caption, the text is possibly too small. I read on desktop, and even for me it's a little small, so I can only imagine that for those reading mobile, it will be difficult to read it.
But yeah!
Good work! (:
