@Pounard, I specifically mentioned the need earlier for all cuts to include a collar, and showed how to do it.

Edit: sorry, wrong user. 

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.

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

@Pounard, when uploading images in a pack, take special care to save the images with the right UID. This image should have been posted here.

@Pounard, good work but there's no need to nudge the collar quite so far up, and you should use the person's own kit (not the Ecuador one I suspect you used here 😉 )

Ah ah! Well seen 🙂 I'll do it again properly

Done already 😉
