I think the first image would work quite nicely with a 2/3 or profile mask. In those positions, the hand would give perceived support for the head. As is, there is too much of a single line along the right edge of the frame, giving too much weight IMO and also causes the hand to be the predominant feature. I would try this again with the chin resting on the ball of the right hand with the fingers angling back towards the right ear. Also, try raising your camera angle slightly. You have distinctive facial features.
Not a fan of the second shot.
