Some say, "You shouldn't shoot directly into the sun". humm...
Dark foreground silhouettes the scene.
In this case, the subject needed fill-light (strobe) so he wouldn't be in deep shade. Love those long shadows from the tree.
Many times a simple reflector can fill the subject to nice effect.

Be aware of the light and use it to your creative advantage.
