I am an artist / writer, but haven’t written in a very long time, (certainly never tried fan fiction). I enjoy reading and reviewing well written stories, typically of an adult nature. We readers know that by checking out the profile of an author of a particularly good and well written tale, we can find links to their favourite lists, thus finding a good source for other great stories. Feel free to do the same from my list of favourite fics and authors.
Regarding reviews: I do try to leave reviews for the stories I read, and any criticisms I leave I do hope are considered to be constructive, not flaming. I only make comments regarding minor things as grammar, tense discrepancies, spelling and the like. Things that are obvious to the reader that may tend to interrupt flow. I may also point out plot points used by other authors if overused, rendering a story redundant.
My appreciation goes out to all authors who have posted stories here on this site, as I do realise any creative endeavour is important to get out for others to enjoy. Thank you all!
