I would scrape the middle 1/3 of the top limb just passed the knot and the first 5 or 6 inches and last 2/3 of the bottom ,being careful to leave the weaker spot on the bottom limb alone. Just a little scraping,looks pretty good to me. How much set has it taken,and are you keeping it good and dry when you ant working on it.
A unstrung profile might help also to see what it should look like at the knot.
