@mr.milanesa, not bad but do keep in mind that every cut must have a collar. At the same time, however, the ideal cut only contains 2-3 pixels beneath the chin. Since in some sources, like this one or the Nagy one, the person in the image may have a longer neck than usual or the collar is lower down, this would be quite difficult to achieve naturally. Here's a technique of how this can be accomplished quite easily, they're perfectly fine otherwise 👏
