I enjoyed this.  It's well written in a technical sense, with varied sentence structure and advanced vocabulary, but also in a narrative sense with some surprisingly well developed characters considering how little lines of text you have to work with in the chapter.  I also appreciate the quasi-satirical style, it made the story all the more entertaining to read.  Good work sir.

An altogether decent tale.  You have believable dialogue and you don't jump into the action before establishing some reputations with your characters.  The technical bits are in good order as well with no noticeable errors.  I'd like to see the descriptions expounded upon a bit more so that your reader can "feel" what's going on, but that's a small complaint considering this is just a first attempt.  Good work.

Not bad at all.  I enjoy the diversity of personalities you have here, and it's a fun set-up; I like the bug bite used as a jumping off point.  Be careful on proofreadings; the errors can be a little distracting in places, and you could probably still benefit from some more vivid descriptions and fluid conversations, but overall I like this.

A very enjoyable premise with some good introductory action.  Keep it up.

Excellent as usual. The dialogue is positively chilling and the action is as palpable as it is sickeningly brutal. I'm normally not a huge fan of gory stories, not because I'm opposed to them, but because most people lose the limited realism factor of these stories in those segments. What you have here is both grounded and descriptive, which makes it all the more impactful. Great stuff here. With your talent for this particular genre of fiction writing, I'd love to at some point see you tackle a story that revolves a bit more around extended torture play that's perhaps even exclusively mental rather than physical, but whatever you do, keep contributing here, because you're very good at it.

It's actually not half bad.  You have a decent premise with good potential for some fun scenes.  I'd think it would be easier for readers to get into if some of the language were cleaned up, but I'm getting the sense that this is more of a language barrier issue than just being a sloppy writer grammatically, because this is actually reasonably clean.  Your dialogue feels sort of stilted in places, but that just goes back to the same reason, I think.  All in all, not bad; perhaps try saying some of the dialogue aloud to yourself, odd as that may sound, to try to find the right tone.  Keep it up.

You have some excellent content here.  Your character development is intriguing and layered without hindering the effectiveness of the destruction segments, which are tantalizingly realized and descriptive.  There's a certain rawness to those scenes that I can't quite place; you capture the violence and brutality of the situations very well.  Your psychological explorations are a lot of fun, too, and you do a nice job of playing off of whatever's going on action-wise in the tale at that point in a way that lets the reader connect with the giantess' psyche while still regarding her as villainous.  Keep it up.

I'm seeing a bit of commentary here regarding ideas of realism, so I thought I'd add my two cents.  There's an important distinction to be made about realism in stories like this.  Obviously there's suspension of disbelief needed on the scientific anomalies/magical elements that these types of stories have to include to make sense, and that's fine.  Unless I'm mistaken, the kind of critiques you're getting here about realism have to do with your character personalities and the logistics of your fictional world.  No matter how many people shrink, you want reactions and events taking place as a result to mirror lifelike human emotion as closely as possible, as that will draw readers into the story better by allowing them to relate to what takes place.  In that way, I can see where people are coming from a little.

That said, you've actually got something pretty decent here.  The situation feels different enough from most of the content I've seen show up lately and you have some fun scenarios at play.  Your dialogue feels pretty varied, too, as you represent a variety of emotions here other than the usual run and panic mode of most shrunken characters.  Keep it up.

As usual, it's very refreshing to see a work by you pop up.  You have a very uncommon sense of how to establish an emotional connection for your main characters very early on without needing a whole lot of prefacing.  I enjoy your works in general but I particularly like those of yours that take place in a roughly modern setting, and this one looks to be a very solid piece.  Keep it up.

Probably the best advice I can give at this point is slooow dooown.  Your story is advancing so quickly there's no time to take stock of what's going on or get wrapped up in the fantasy elements.  You say you're not going to give many details because you're not sure what people want to picture, but the point is you want to show them what they ought to be picturing by giving enough detail to let their imaginations do the rest of the work.  It's a decent premise and not one I've seen much of but at present it's sort of a mess with many grammar errors and not much reason to continue on past the first segment.  It wouldn't hurt to comb back through what you've got and smooth out the errors while also massively beefing up the detail.  Just my two cents.  Happy writing.
