I think you might hvae a nice idea coming along, although your story (chapter) is really short but this is not the main issue. Tha manin issue is the paragraphing. You should work on spliting up your story into paragraphs because it makes it much easier to read.

Marian mentions she comes from a planet orbiting the star Algol. I did a bit of reading, and this apparently lone star is actually part of a systen containing three stars and as such, this would make it very hard for a planet(s) to exist because of the effects of gravity. Any planets that do not want to be flung away would to have to be so close to the that star they would be too hot for any life.

Cool! The cat fight has started.

Here:

err, "acquaintance" of me.

You mean "of mine".

And here:

We know each other for a long time, and I can tell you I cannot express my dislike or my desire to see her vanquished.

I think you mean:

We've known each other for a long time, and I cannot stress enough how much I dislike her or my desire to see her vanquished.

I did notice a few plot holes but I think I'll leave it at that.

It was really good until Jen said she likes feet. I felt it was rather out of character if I'm honest. She comes across as very shy and then suddenly she makes a bold statement about wanting to see Tanya naked which I thought was misplaced but I can't complain too much because it's your story.

I'm struggling to understand what Johnny did wrong to merit being shrunk. I don't think that was explained. Johnny is a nice guy, he didn't need to be shrunk, Seems a bit too drastic.

I was a little wary of the 'giant men' tag at first (this is giantessworld after all) but I have a feeling this could be a good story.

Can you please split your story into paragraphs. It would make much easier for people to read. At the moment it looks very daunting.

Wow, this is quite interesting. I like the ending to the chapter.

Hi Veronica, welcome to giantessworld!

Wow, lots of new authors lately, this is awesome!

So I've been reason your story and spelling and grammar is pretty good although some bits were confusing. Like here:

"but she didn’t, her smile was that of concern." A smile is a happy emotion so I'm not sure smiles can show concern. I think you mean (facial) expression or look. Smile is the wrong word to use here me thinks.

Also, if Diana is Tim’s girlfriend why would she suddenly stop caring about Tim. I honestly thought that was a little odd and if turns out she doesn't like him then perhaps there should have been more of a build up to him being eaten. And it seems rather out of character of her to randomly put him in a sandwhich if she is his friend.

Here: "Tim understood and started to sulk off."

If Tim understood he wouldn't really sulk. He would maybe try to make conversation with Lilly whilst she prepares the food.

The end was really sudden and rather weird, I'm sorry. Not sure how he can instantly assume all these events are because of a trip to the mall two days ago. It almost felt like it was an afterthought thrown in at the end to quickly try and explain everything.

I hope my comments weren’t too harsh but I know you have lots of potential as a writer, and more you write and more stories your read the better you will become. I hope my comments were useful but if not then that's ok too. I wouldn’t want to discourage you from writing.
