Why do I hate these colours together?

I bought a mystery FQ bundle on Black Friday and am, at last, gonna make something with it. But I’m really struggling to love the fabrics together. The white fabric is my background and I need to add 1 more FQ for the pattern I’m making (Hidden Shapes - last picture) And I feel like finding the perfect colour will pull them all together but am stuck. What do y’all think? I’d love to add an orange to pick up the little flowers in the bird fabric but they all look goofy. I’m open to anything. Even only using a couple of these FQ and starting fromi scratch.

I also need to add an accent colour for the square in a square blocks and picture 2 and 3 are a couple of options for that. Thoughts?

I feel like it’s all so brown at the moment…..
