The arms are sculpted basically the same as the legs. The big differences are that they are smaller and the elbow bends in the opposite direction of the knee. Refer to the pictures for the basic shape and size of the arms. The toes and feet are exactly the same as on the hind legs, just a little smaller. When joining the arms to the body use a small amount of TLS on the inside of the upper arm to make a good seal. Blend the top of the shoulder into the body so it doesn't look just stuck on. On any areas where legs where joined re-apply texture that has been flattened out.
