@O BRABO do vdg, there is too big a gap above the head and too much of the person shown below the chin. It should be no more than 2-3 pixels in each case. Can we have the original source image for this so that it can be recut please?

If you want to start producing cut-outs, have a look at the guidelines in this thread, as well as the many video tutorials for each technique. I recommend using remove.bg to remove the background from an image as well as photopea.com to tweak, both free tools which do an excellent and quick job - watch the tutorials in the above-linked thread 👍
