Welcome back! Two thoughts, yes, your cto suggestion would help, and you're going to probably smack your forehead with the next thought, the perfect light for your shot probably happened about 20 minutes after you shot the one we see here. You can avoid all kinds of problems by timing a portrait like this to just a few minutes after the sun drops below the horizon. You can still kick in a little strobe in a soft box if you want to punch it up a little, but once the sun drops, you have a huge natural soft box as your main light. Portraits with direct sunlight are a technical problem, and rarely enhance the subject. In fact, I have a 5'x5' diffusion frame that I can mount to a Matthews stand for situations where schedules won't allow the appropriate time of day.
Next time you're outside at sunset, watch the change that takes place just as the sun sinks and becomes "bounce" light. Sometimes, when you have a really hazy sky, but no clouds, you can get away with a portrait before the sun drops and get pretty much the same effect. None of this will help you fix what you don't like about the existing capture, but put it into practice on the next one and you'll love it.
