better size

It's a good cut, but it's best to only leave 2-3 pixels beneath the bottom of the chin. This way, the focus of the cut is the face as much as possible

I did it to avoid the chicken neck effect .
Wanted to include some collar in it,maybe i overdid it .
Though on the right side,there's not much collar included.
Some people have long necks which is not ideal for the cutting community .
Some other cuts of me,i've recently done having the same issue .

I know what you mean, but this particular source image's collar was positioned in such a way that it could easily accommodate the collar while not leaving such a large space. And in cases where the neck is overly long, there is a quick and effective technique in the guide to cutting thread on how to work your way around it

This is the first one I've seen, but I do have around 400 cuts pending atm, so I might have missed it.
