if your chracter is too perfect or if he/she is perfect but with a terrible past and no one can relate to her at all. she may come of as perfectto the creator but to others she leaves an evrlasting impression of "annoying, and too perfecct" if your chracter is going to be perfect make sure the writing is deep and detailed, if its not then it will come of as ameture
