These aren't bad cuts, but they have been cropped much too far from the top of the head and the bottom of the chin. You should leave no more than 2-3 pixels in both instances, as outlined in the guidelines. Please keep in mind that, at the same time, all cuts should include a little bit of collar. Since in some sources, the person in the image may have a longer neck than usual, this would be quite difficult to achieve naturally. 

Here's a video displaying a simple technique of how to cut close to the chin and still display a bit of the collar:

Here's a couple of videos on how to use remove.bg, one when combined with Photoshop and another using photopea.com, which is a free online app so close to Photoshop that it has the same shortcuts, layout and icons 😉 If you don't have Photoshop, photopea.com is the tool I would recommend to use to tweak the draft cut produced by remove.bg. It's more powerful and versatile than GIMP and other similar tools.

Also, when you have multiple images to upload, please do so as a pack instead of individually, which makes life easier for the both of us.

I've produced a cut for this player from this source so that you can see what we're looking for. There was a bit of snow, which I removed using this technique:

Ohh oki, I'm so sry this is my first faces cut try… Anyway, thanks for videos i try do it better next time 🙂

Your cutting technique is fine, it's just a question of rotating them, nudging the collar upwards where necessary and cropping them closer to the actual head 🙂

Take a look at the guidelines and tutorial thread for more info 👍
