Where the arm meets the torso (armpit) is a high-stress deformation zone. You need a "star" (a vertex where 5 edges meet) to redirect topology from the torso down into the arm. Do not connect the pectoral muscle directly to the deltoid with a straight seam; use an interlocking "Z" pattern of quads.
Use spheres and cylinders. Get the global proportions perfect. Is the character 8 heads tall? 7? 6.5? Lock the camera. Do not rotate for 10 minutes. Just check the side profile.
