Photographically amputating a portrait subject at the joints is a definite NO, NO. You have cut her off at the elbows in #1, elbow and wrist in #2, elbows in #3, etc. A straight on photo makes a subject look more like a football player which is not flattering for a woman as in #2, and #3. An angle to the shoulders would be more flattering. As mentioned a fill flash or a reflector would result in a better shot. The background in number 1 is too busy and could benefit from less depth of field with the requisite f. 2.8 to 3.5 approximately.
