I would take the blue bird and stem and reverse them and applique them in the top right as if they are a tree branch and bluebird sitting on the tree branch.
It would add symmetry and balance (two things I've learned this past week are necessary in quilts - from a certificated quilt judge). You may never submit the quilt for judging, but over time something symmetrical keeps its value ("I like it"-ness) longer than something off balance.
