Not a bad start @upthearse but do have a look at this thread for guidelines for cutters and video tutorials on what we expect for from our cuts 👍 The edges are a bit jagged and not as smooth as we'd like and it's cropped too far away from the chin. I've redone it so you can see what I mean 😉

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.

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.

We ask for all cuts to contain a collar within no more than 2-3 pixels of the chin, and for them to be cropped no more than 2-3 pixels above the head.

If the source image contains a collar which is lower down than that (as in this case), use the below technique:
