I like #3 - it reminds me too of the sunset on the beach. Plus the palm fronds extended up into the border that color will look great.
#1 - all I see is border & the palm tree trunks. Dark, no lightness, & never even looked up at the palm fronds.
#2 Would be ok - if you weren't going to extend the pam fronds onto the border. Too much green
But hey - that's just my opinion! Take what works & leave what doesn't. Will be neat to see your finished quilt & see what you did.
