I honestly didn't find this chapter all that enjoyable. There were some good things about it, don't get me wrong. The premise of a Sphinx posing as a school statue was good, and I do like your attention to detail when it comes to the new body locomotives and mechanics. They feel very real and natural.

With that said, I do think there are too many details in this chapter. I understand that you want to convey everything as new and alien, but too much description can be harmful to the story. It distracts the reader and turns into filler after a time. Also, these characters never clicked with me. The main character isn't distinguishable in the slightest, and comes across as a generic transformation victim. There isn't anything unique about her other then she shows a lot of school spirit. That's good for acting as a catalyst for the transformation, but it leaves her with little else. Her mother also conveys little emotion to make me believe she cares about her daughter's transformation. She's too calm and to the point. I know four days are supposed to have gone by, but what parent would go into their transformed daughter's room and calmly tell them to come down and have dinner? It didn't feel natural.

Now, I am aware this is the first chapter, so I will not judge the entire story off of this. I am simply stating that there are a few problems to be fixed, namely with less unneeded details and developing the characters. There is a lot of potential for an interesting story here, especially if she's been exposed to the world, so I do look forward to seeing what will come of that. But these problems are very apparent.

Thank you for the feedback and drawing attention to such glaring problems. I will look into making some revisions and characterizing more throughout the chapters. I eventually want to have the mom be almost "supportive to a fault" or like treating Raelena like she's some delicate little thing that eventually. But that doesn't deny the fact that I may have missed the mark and I will try to fix this if I can. I'll also look for places I can trim down on the detail a bit.

I have made some minor edits to this chapter, getting rid of some excessive detail and changing the dinner scene a bit in keeping with my plans for the characters. I don't think it fully addresses all of your problems, but hopefully some of these things will become more clear in later chapters when I get to them. Also, as I've been dwelling on your feedback, it makes sense (at least from my standpoint) for there to be so much detail this quickly after the change that would taper out over time. There are a lot of new experiences that would warrant additional attention to her. Though I have always been attention-detailed in my writing, I think the over-emphasis on detail will start to dissipate soon.

Though I'm not entirely sure how the story looked before your edits, I must comment on how proficient and flowing your story flows now.
Many of the details are crisp and exquisite, and I'm left wanting to read more. Quality work, my good sir. You've done a wonderful job.

I always enjoy Sphinx transformations
