(Especially grammar, I can get most words right, but I can't hear where to put ',' or how to separate sentences nicely.) I have searched the web for any image that could properly portray our protagonist while keeping it free. I have found a very nice picture that was close to what I was going for, but it IS AI-generated and I have no idea how copyright works. I do not own that image, I have simply searched for a free picture describing her features and found this... if you are the owner of this picture, please write me a message and I will take it down as soon as possible. (The Image is temporary and I will commission an artist later for a more accurate depiction~)
