@Tuckius:

a) for future reference, when you have a lot of images to upload, then you should upload them as a pack instead of individually and save the both of us some time.

You can also upload up to 50 images per pack instead of just 6 when done individually.

b) 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.

It's best if you recut this one given you've removed it completely from the cut, and adding it again would take more time.

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

c) Consider brightening and/or auto-contrasting your cuts as they are somewhat unnecessarily dark 👍
