The goal of The Incredibles group gallery is to showcase as many pieces related to The Incredibles as possible from those available on DA. However, there are thousands of pieces and it takes time to search for and request those pieces.
Many of the pieces that have been requested belong to deviants who wish their pieces not be submitted, or to deviants who are no longer active in the DA community or have even been banned. Among these are very good pieces that, for whatever reasons, don't make it into the group gallery.
It is suggested therefore, that you may wish to search for pieces related to The Incredibles as well.
I have no idea what any of this has to do with being on a fixed income.
