Hello Moya,
A few friends mentioned that Seeing Wings of Green is, in many sections, an almost direct copy of Upon Wings of Change.
Your summary does state that it was inspired by my book, so credit is given, and I won't submit a copyright takedown notice, but I will kindly remind you that fanfictions allow you to use the universe and world building (and I made special exceptions for the kidnapping/science lab part, so that may be used), but a fanfiction isn't supposed to copy all the plot points, and notably should not copy entire sections of the story itself.
I admire your enthusiasm and recommend taking a second look at the story and seeing how you can remove the copied sections to make your fanfiction less of a direct copy.
Thanks,
Crystal
