Do you have any of Eileen Wright's books? She gives really good advice for picking out fabric for a Bargello. She does say to include one fabric you might think didn't belong, calls it a zinger. With the rest of your fabric selections going from light to dark, you could probably get away with this fabric.
Many of her patterns suggest 20 fabrics ....ten from one color group and ten from another, but each color group going from light to dark. You could sort of select two of those colors and then throw this fabric in as a zinger?
Let me see if I can find pictures of two of mine where I included a fabric that had a bigger print than I really thought I should use. In each case, it gave an interesting slant. These are sort of from a pattern called Serenity...though I changed them up a bit when I made them. (These two are not from Eileen Wright's books, though my favorite from her books is called Surf Song.)
Here is a free copy of the Serenity Bargello pattern:

Here are two of my quilts, each with a zinger...though I only used one color family so my zinger isn't too different. Okay....I found three instead of two....
But I like Bargello quilts. (I have made 12).
I hope some of this may give you some ideas about what you might want to do with your beautiful fabric!
