I don't have any expectations for anyone who wants my service. I will read absolutely anything and give an honest opinion on it. When I betaread, I pay special attention to how sentences sound. I pay close attention to wording and what flows the smoothest.
I don't just change what you have, I am here to help you improve as a writer. So, when I betaread, I will tell you what needs to be changed, why, and some suggestions as to what it should be changed to. Since I specialize mostly in grammar, sentence structure, and wording, I will probably have you revise quite a few of your sentences. If this is the case, then I don't mind checking something over a second time, after you have corrected it the first time.
That being said, I will warn you that I am harsh when I criticize. However, I am just as ready to compliment you on what you did well, and tell you of your strengths. I believe that it is important to understand your strengths as well as your weaknesses.
I suppose my services would be ideal for people who don't speak English as a first language, or who struggle a lot with writing. Perhaps even someone who is new.
I'll read just about anything. Yaoi/gay (boyXboy), yuri/lesbian (girlXgirl), hentai (boyXgirl), incest, blood/gore, extreme sexual content, BSDM, extreme lemon, or various forms of polygamy (including threesomes). You will very rarely find something that bothers me.
