hi, had a look at your pictures, and they look ok, but im slightly put off by the facial expressions (1st more than the 2nd), i like the pose in both, i think the 2nd would benefit with a slightly lower crop, as in just above the knee, i also feel the top looks a little low in the 2nd shot.
i like the tree in the forground of the 2nd shot
the lighting looks good, was it natural only?
