There are many people who would love to have this degree of sun flaring! The look you have is popular these days with a good many people. If there's anything I would suggest it would be to apply very subtle darkening around the edges of the frame, and to perhaps increase the maximum black level a little bit, so there is a bit deeper maximum dark value somewhere within the frame. That will tend to bring out the look of the flare against the dark parts of the frame , like for example in frame #2, where the flare is near his jeans. Shot #2 would probably look better seen a little bit darker overall, a with a deeper black point.
