A benefit to shooting portraits in bright natural light is that the subject's pupils will remain small, allowing the eye color to dominate. The natural light sources reflecting in the subject's eyes may or may not be an asset.
When shooting tightly cropped portraits, I usually want the chin to remain completely in the photo until cropping extremely tightly.
