Do you have a tiller tree or board? Put your bow on the tree and draw to this length. Take a straight edge of some kind, 4 inches or so, and run it along the belly. The gap will tell you if it's flat. It either is or it isn't. Your getting close to the point where 10 different people can give you 5 different opinions on what they see and how to proceed. The straight edge will reveal truth. Does the gap agree with your feeling about the flat spots you see? If so, scrape until they are no longer flat, 10 scrapes, exercise and check the gap, repeat until you've evened out the gap. I think you look better in the latest pic. I also think you could be getting hingey both limbs, 6 inches from the handle. Does the straight edge confirm this diagnosis or reveal something totally different? Fix what you find at this length and then draw it a bit farther and check it again.
