Not bad @zeedan, but what program and technique did you use for this cut?

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. 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. 

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, please keep in mind that we want every image to have a collar and we want it to be no more than 2-3 pixels beneath the chin.

In cases like this where the collar in the source image is lower down than the bottom of the chin, it should be nudged upwards to be within 2-3 pixels of the chin as demonstrated in the below video 👍
