Disclaimer: I like bright colours.
I often use the "squint" test. Stand back from the quilt a bit and squint at it. One of the colours or tones will sort of jump out at you more than the others. I see the orange tones when I squint at the picture of your quilt.
In the third picture, in the bottom left log cabin, there is a lovely orange and yellow batik. I'd make a narrow border of that and then a wider border of the brown with the orange and purple polka dots. Then a plain dark brown binding.
JMHO!
BTW, the squint test works really well when arranging lights on a Christmas tree - just squint at it and the holes where you need more lights can be easily seen.
