@LFCYNWA, good attempt at this source.

Allow me to give you some pointers, however 😉

a) In sources where the image is tilted to one side, it looks much better in-game if the cut-out is upright as possible. So rotating the image before cropping it, in this source by perhaps 6-8 degrees clockwise would help a lot.
b) You seem to be aware of our rule to have only 2-3 pixels beneath the chin. Just so you're aware, we make an exception in cases like this where the hairstyle is a bit large. In these cases, we aim to have as much of the width of the hair included as possible. Since this may mean that the distance between is a bit bigger than the ideal distance of 2-3 pixels, we then try to have a little bit of space above the hair and the same amount beneath the chin
c) I know you only recently start cutting but I'm afraid the fine hair details aren't very clear. What program and technique are you using? Have you had a look at the guidelines to cutting thread? Putting the source from the above link to remove.bg gives a great cut with loads of hair detail and very little work required. All you'd need to do is rotate it, crop it and resize it. And in the case of this particular source, some judicious stamp of the clone stamp tool to recreate the missing bit at the top of the hair. I'll provide a cut of this guy when I get home from work later today to see what I mean. With remove.bg doing all the hard work for you, you can spend less time to improve better cuts, so well worth considering its use, which is most importantly free 😉

GREAT tips, especially about remove.bg! (I've been using paint.net all this time, and I'm trying NOT to calculate all the hours wasted scooting my mouse along a pixel a second.)
