I wouldn't stitch too much around the raw edges of the roses, because you want them to fray and soften up, right? Maybe a simple meander around the outsides. I don't think a "simple scribble" would steer you wrong; you don't have a lot of open space to quilt and you want the main focus to be on the roses.
I agree with Maniac, depends on your batting. Lovely quilt.
