Good work @justt. For future reference, cuts shouldn't have more than 2-3 pixels beneath the chin/facial hair. This is to ensure that the focus of the cut-out is the face as much as possible.

At the same time, care should be taken to avoid the chicken-neck effect and so all cuts should include a little bit of collar. Since in some sources, the person in the image may have a longer neck than usual, this would be quite difficult to achieve naturally. This video & this post & this post too display a simple technique of how to cut close to the chin and still display a bit of the collar.
