Wow K, this is so cool! I have to say that I wasn't very appreciative of role reversal until I started reading your work, but this is another example of what I consider its transcendent quality.

In the introduction, we learn that Nicole is independent and confident, and that she places value on appearances (or at least, she understands their value - and their limits). She sits in the driver's seat. It is her habit to objectively assess social hierarchies, and to climb them. Altogether her voice suggests someone who is naturally inclined to dominance, and this means that being shrunken and powerless is a role-reversal for her, right from the beginning.

After Nicole is shrunk, there's still a bit of defiance in her tone. While she's terrified at first, she seems to channel her energy to anger very quickly, then go from anger to cold analysis. The scene had a sense of "wrongness," in that being tiny and powerless is not Nicole's rightful place in the world.

I loved that Nicole got to watch Dana show her dominance over the other girls from a tiny perspective, demonstrating that Dana had power over other people who in turn had power over Nicole (at the time.)

Your love for shoes comes through strongly in this scene, and it works well! Nicole's vivid descriptions are natural and organic at a time when the shoes around her are effectively the most important things in the world, and require her full attention.
