Either the pants highlight is too bright, or the shirts highlight is too dark. Probably in between.
Considering the sun position, only the right side edge of things should get direct light, so the main middle color should be blue shifted too.
But you might also consider moving the sun (> out of the picture).
I don't get where the green in the pants come from. In grazing light, most of the color is from the light source, and very little from the lit object.
The hat lighting is very different, from the front. Also the right side is curving up, so should cast a shadow.
The shadows on the ground should be blue shifted too, and should point straight away from the sun, and diverge too.
