I actually think the guy on the left is great, true, he has subtle traits, but the traits really stand out and make a clear message on their own, I think it suits him well as an officer : ) lol before reading your comment, I thought the guy on his right was his dad
mmmh sincerely I don´t like de changes it seems like you only stretched the first image, maybe with some other exagerations or maybe if the rotation of the body is more obvious... sorry, I admire your work, but I can´t lie about what I see.
There is something more "official" about the one on the left. The one on the right looks like a caricature of the one on the left. Not sure which I prefer more. Depends on what he'd be used for I suppose.
