This portrait is of a dancer and aspiring fitness model. It is beautiful, not just because of the gorgeous sunset, but because it captures both the impressive musculature of the subject as well as the delicate posture and softness of the subject's dance training.
It was taken with a Nikon D3400, Nicor 35 mm f1.2 lense. And the subject is lit with a Speedlight bouncing off of a 32" silver reflective umbrella
