Good work @tochalius and I'm happy to see you taking on these sources yourself :clapping_hands:

One small thing to keep in mind, though: There should only be 2-3 pixels between the top of the head/hair and the top of the canvas, and the same distance between the bottom of the chin/beard and the bottom of the canvas. Care should be also taken to avoid the chicken-neck effect and so all cuts should 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 or the collar is lower down, this would be quite difficult to achieve naturally. This video & this post & this post too display a simple technique of how to cut close to the chin and still display a bit of the collar.

Basically, you lasso a bit of the neck/collar and nudge it upwards. It takes 10 seconds and the cut looks much better and more in keeping with the rest of the megapack 👍
