Everybody has their own preference. But for me, this is misleading feedback. Because you are getting nearly identical highlights in both the valleys and peaks, due to lack of shadows in the valleys. Also the shadows are going in opposite directions. On left side of the surface, they fall on left side of the peaks. On right side of the surface, they fall on right side of the peaks. There's nothing wrong with it. But it's somewhat unnatural to me...
