@johnloch, please keep in mind that we want all cuts to include a little bit of collar, as I believe has been explained to you already. 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:
 

In cases where the source is tilted, like this one, it should be rotated in order that the final cut is as upright as possible, which looks much better in-game. Here's a video of what I mean:

Please make sure to keep this in mind for any cuts you upload in the future 👍
