Curves like that should only exist in centerfolds. Excellent work. Don't scrape anything.
As far as finish goes, I have trouble staining bows. I'm not saying it shouldn't be done, but if you want to see your bow's natural beauty really shine, try rubbing boiled linseed oil on her about 4 times, with about 20 minutes between coats. Then give it about a week to really dry, and finally you can finish with your tru-oil. I haven't used linseed oil on osage before tho, but from what i've seen at the lumber store, it looks like it would react much like yellow heart. And if that's true, you won't be disappointed.
