@fajar agung, good work but there are some tweaks needed to your cuts. Perhaps you can re-cut the ones I've left pending with the below in mind.

a) Leave no more than 2-3 pixels above the top of the hair and beneath the chin, so that you use the full height of the canvas as much as possible and let the face take up as much space as the source allows.

b) When a source image is tilted to one side (as in this case and a few of your other cuts), then it should be rotated so that it looks more upright before it is cropped, because the cut looks much better in-game in this way. Watch this video to see how it can be done:

Thanks for your appreciation. can I get another alternative link? 

It's working fine for me, can you not see it? It's just a short video and all it does is show how to rotate an image so that it's upright.

This image and this image can also serve as practical examples of what I mean, in that the source was tilted to one side but the final cut is upright.

@fajar agung, you've increased the gap above the top of the hair instead of decreasing it, and not rotated it 😕

If you upload the original source, I'll cut it so you can see what I mean.

sorry, I'll try my best next time.. hehe
