@Jakub Špendlík Good cuts, but please remember that we want all cuts to include a little bit of collar. At the same time, the ideal cut only contains 2-3 pixels beneath the chin. Since in some sources like this one, the person in the image may have a longer neck than usual, this would be quite difficult to achieve naturally.

I'll fix these myself, but please keep it in mind for any future cuts you may do 👍

Here's a video of the process on how to nudge the collar upwards:
