I think Prism has given some good advice. If you do not want to rip the quilting out (frog it), then do as Patrice suggested and block it. Then quilt it some more. I have had to frog an entire Qu sz that was pretty heavily long-armed before. Not fun but not that bad while watching a movie. This quilt doesn't look that bad. IMHO I think I would block it and maybe do some more quilting in it and call it a day.
FYI: If you ever try Bamboo, it does shrink more than Wool.
