BeauxArts is a small elite design studio. We have limited talented people and as such we cannot accept every project. This doesn’t mean you are a bad author. It often means there are only so many hours in a day and we are swamped.
We also do not accept certain work because it doesn’t fit our creative scope. We don’t do comic books, for example.
We also prefer to work with genuinely happy and pleasant clients. BeauxArts has dropped a few clients in the past because they were difficult individuals to work with.
