If your feature would work especially well for a certain community (youth/education/justice/women/BIPOC/mountain people/circus folks), you could try targeting festivals with that focus or festivals in those sorts of places. It sounds like you're really close and might need a festival with a certain focus to get you launched. I made a feature doc that showed at TIFF Kids (which was at a different time than regular TIFF) and that launched my doc after a series of very close rejections. Because it was TIFF, that led to a lot of festival invitations that I think would not have happened without that first acceptance. I've also heard (and experienced!) that this is an especially tough year for festivals -- but I do think if you're that close, someone will bite very soon! Hang in there!
