You’re right it happens to me many times when I don’t have an idea or when what I have is not quite good.
I intend and am thinking of creating an OC Pony and Equestria Girl version, in my profile I published my OC that is Milkyboo but Equestria version, in the same way I am not convinced and I want something more appropriate for the Equestria Girl world.
I planned to combine several things that my OC Milkyboo has with some Equestria already created, but in the end I know that what I am looking for will not come out, maybe someone can give me some interesting idea to take into account. One of my favorite anime is Uzaki and Tejina-Senpai, I also planned to have my OC with short, white hair with glasses (since I love glasses girls), but I haven’t put it into practice yet.
