@Debenja Good cut, 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 this one 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:

@mons I just can't understand it.

If I compare my image to yours, same pixel height top and bottom. The difference is the position on the horizontal axis. You've refocused the image. I had the same thing yesterday, but the other way round, I'd centred the head and you'd moved it off-centre. I can't understand the correct position of the head now 🙂

I still need to find the right brightness/contrast that you want on the faces. 

There are 3 things that I did to tweak it:

a) I centred the image in the canvas. Yours had a lot more space to the left of the head than it did to the right:

b) I added a collar because yours didn't have one:

c) I used the auto-contrast feature and/or the brighten image function (can't remember which). There isn't any right or wrong way for this, really. Yours is fine, I just thought it'd look better if slightly brightened.
