@Juancho07, if you want to upload images on the forum, please make sure to read the guidelines and follow them. If there's anything you don't understand, just ask. You will need to re-cut all the images I rejected, keeping in mind these guidelines as well as the feedback I've provided here and elsewhere.

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.

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