This will probably get moved to the Critiques Forum.
You did good on skin smoothing, especially on the face. Not a lot of texture can be noticed, neither before or after, so I won't comment on that. But the after has more visible uneven tones than the before, with a more pinkish tone in the face skin and hands. Playing with the contrast slider could have done that. What is too much is the logo and the text that I feel ruin your image. Both logo and text is blow-up in Photoshop and makes those jaggy edges so visible. Text can be any size in Photoshop, logos can be traced, but it takes some knowledge of the pen tool and patience to do it. I'd also suggest learning pen tool for extractions, although yours would have worked just great with select color+del, but it is very obvious you used a large soft brush as an eraser, from the shoulder that blends in with your logo on the right side.
Also, and this is likely just a matter of preference, but I think military images look best on location or with backgrounds swapped in PS if done in studio
