@nawaf044, before uploading any more cut-outs, please make sure you take a look at this thread for guidelines for cutters and video tutorials for some more info on what we expect for from our cuts. Your cuts are cropped too far from the head, have wrong dimensions or have poor aspect ratio. Before uploading any more cuts here, please upload them in the tutorial thread together with the source image so that we can give you specific feedback in order that you can improve your cutting technique moving forward. The ones you have uploaded aren't really good enough, I'm afraid.

I recommend using remove.bg for your cuts. It's a fantastic free online tool which does the heavy lifting for you by removing the background in the source image, leaving you to only rotate, crop and/or nudge the collar upwards. It's tremendously easy to use and provides fantastic quality. With it, you can go from source to cut in a couple of minutes for the vast majority of images. If you watch this video, it should address all your queries 🙂

Here's a couple of videos on how to use it, 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.
