red = retopo
green = new edges that need to meet at a symmetrical edge, or turn into a tri.
blue = new edges that aren't needed but keep the breast topo even around the nipple.
magenta = triangle created as a result of one of those blue edges, but i don't think it will cause many issues, as it's on the ribcage, and the ribcage doesn't deform very much if ever.
As for the other blue edge, i can't see where that could merge into a tri, but again, somewhere just below th breast on the ribcage shouldn't cause much issue.
