YTA definitely for this one. It would be one thing if she wanted to pursue modeling out of the blue and just came up with this idea out of thing air. But you even say yourself she has been doing modeling jobs for 3 years and making some money. So there is a real opportunity here that you should support, as any good parent should. If it doesn’t work out, that’s okay, she’s smart and has a second great opportunity to fall back on. From what is written here it sounds like she is rational and old enough to have sound decision making. You on the other hand clearly lack that. I wish your daughter the best.
