Hey Nelson, so the edge loops only sharpen in the direction parallel to themselves, which is why the angle between the side of the cookie and the top of the cookie (parallel) will be sharp but the bite marks (perpendicular) will not. Notice how the top, bottom, and second to bottom points of the bite marks are sharp because you have two close loops crossing in those areas. If you then add that to the other points (this is shown in the video if you follow the topology exactly), everything will be nice as crisp. Hope that helps!
