Hi Kelly,
I'm afraid I'm somewhat the bearer of bad news.
You provided us two good high res photo's but there's a huge obstacle, namely the conflicting lighting of the two photo's.
The family photo I will call A is taken under the tree canopy casting a diffuse light on the subjects with no facial shadows. Vaguely there's some light coming from the top left side, away from the tree canopy.
The photo is evenly lit.
The photo of your husband, I will call it B, is a nightmare for every retoucher.
It is taken at high noon in full sunlight. The very hard light is coming from the top right side casting a lot of hard shadows, particulary facial shadows.
The next picture is how I suppose you did wanted the composition
You see now the conflicting lighting making the blending unnatural.
Maybe you have or can make a new photo of your husband in the conditions of the family photo?
