The lighting is a bit harsh. What kind of setup were you using?
Just a relook at the first.
Note that the hands and lower arms are quite bright because they are closer to the light.
And the light is so harsh that any skin wrinkles, pores etc are emphasized.
The background is irregular with blobs - and there is a lot of it.
I would change all those things as much as possible to soften the impact.
The smaller the light source the sharper the shadow.
Thus edges on pictures shot in the sun are sharp because the light is minimally diffused by the air... do what you can to diffuse the light thus making a larger effective light source.
You should know where to buy large diffusion screens cheap.
