What an interesting design - very eye-catching and with that white, it looks fresh and spring-y.
I like to use curvy quilting almost always, especially with angular blocks and rows. You could do a simple all-over design with curls and a curvy teardrop with petals on the outside curve, then echoed, bounce into a curl or two or three then start another curvy teardrop, etc. (It's a paisley, but that sounds a lot harder than it is.
)
Whatever idea you like, draw it over and over on paper or a dry erase board until you feel no hesitation at all about where to go next - no anxiety. I don't know why this works so well, but it's like magic, especially on a longarm where you actually are "moving the pencil on the paper," instead of moving the paper under the pencil like you are when you're working on a domestic machine.
Whatever you decide, it's going to be a beautiful quilt!
