....and also remember the rules of thirds when composing your image.
I agree with everything Scott wrote (including info on the shadows). For both images I see here, what I do for horizontal images with a subject facing sideways is this: if the subject is facing to the left, position them closer to the right side, not the left. And vice versa...if the subject is facing the right, position them on the left side. Otherwise the image looks unbalanced because the subject is looking off the side rather than
into the image (if that makes sense).
And in one of Scott's replies, he suggested a vertical crop. That would look better IMHO. Just not dead center.
Move the subject
just slightly off center for a vertical crop especially when the subject is looking sideways.
