I was going for complimentary to the scene & to the model, not in the strictest sense of the word, I know the color wheel as well as the next man. Sheesh!
Yellow and green are not complementary colours... your model should have worn a red coloured shirt to provide complementary colour contrast in this nice portrait.
With a tad differentfocus, this could really be something. I feel as if the shirt is a bit more clear than the face. Maybe that was your intent, as the yellow and green are the complementary colors. For some reason, I like the sunglasses too. The crop is good and I don't even mind him being so centered in the shot. The dappled light is pretty and the DOF is well executed.
