I frequently create male characters inspired by men I’ve seen in the real world. One example is this one:
The real-world person was uncredited for his work as a stuntman or extra appearing in one episode of a certain science fiction television space adventure series you may be familiar with that features many young military types. Using the DAZ3D studio app I created a face based upon the guy’s actual facial shape. Since a facial shape is not something that can be trademarked or copyrighted, you can expect to get away with doing this, too, if you use the DAZ3D studio app.
Compare the reference image of the guy’s facial shape with how this newly-created male character turned out. The faces always are approximations only and may not look 100% like the real-life person. I made certain to be as faithful as I could with this guy’s skin tone. I gave him an impressive body in excellent physical shape. I also made him nude, which is not something easily found today in most Hollywood publicity photographs!
Once I create a male character using this established workflow and process in digital illustrating, I take it to the next level. I then create a visual story that can be told about that particular male character and insert him into it. Here is a modest example. I have staged this male character in an image of a left-handed knight with a very long sword. I left his hair style as is so you would easily recognize the character even in costume. Doing so does mean he does not represent the most authentic look you’d expect from a knight.
