Wow, I am intrigued. I never expected to see the great Panzer write a gentle story and a lot of the tags are eye-raising. As if a gentle story with violence and gore were not surprising enough, there's a tera tag on this thing. I'm very curious to see where this goes (I have a feeling she's going to save Earth from an asteroid or alien invasion at some point, but we'll see). 

I always try to make my reviews constructive, but frankly there is very little to improve upon so far. There were a few places where a hyphen was missing or I felt the phrasing could have been marginally better, but your prose is exceptional and you do a great job of painting scenes without writing a full paragraph of imagery that would disrupt the story's pacing. Seriously, the writing quality is better than most of the stuff at the front of bookstores nowadays. My nitpicks are extremely minor, like why a 500 foot-tall bank apparently has 150 foot-high ceilings (presumably closer to 100 feet since Maxima was crouching) or why SWAT officers would be wearing "riot gear" as opposed to tactical gear (big difference), but these are really superficial things. 

As for what you do well: the list is abundant. As mentioned before, your prose is exceptionally good. Your attention to detail with scales is immaculate, with the 150 foot figure being my absolute favorite in the genre (and one I've employed extensively myself, so I know your math on the "little people" in her midst is accurate). The worldbuilding is a perfect paradox of absurdism (appropriate to the genre of superhero fiction) combined with a degree of realism that makes the setting feel both believable and humorous. You've done a great job of introducing the protagonist, but you've also maintained a level of intrigue that keeps much of her past, powers, and personality obscure (though I expect we will learn more in future chapters). Frankly, I could go on and on, but I want to keep this paragraph somewhat brief and I don't want to risk causing you to overthink anything. Suffice it to say: great work! 

I'm looking forward to future installments. I'm a little curious how much you have outlined already and if this will be a novella-length work or a proper novel (it feels like the latter). Admittedly, I am not a big fan of gore or superheroes, but I've added this story to my favorites and intend to read every chapter so long as I am capable of doing so. 

I also saw that you mentioned adding pictures at some point. Would I be correct in assuming that Gravel will be furnishing some more great art for you?
