@Drazen83, have a look at this thread for guidelines for cutters and video tutorials on what we expect for from our cuts.

These images aren't game-ready because they have a white background and because they aren't in the correct dimensions. I've requested the full-size images so that they can be recut in 250x250.

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.

@Drazen83, crop the image to an area closer to the face before putting it through remove.bg. This way you'll retain the image quality:

Also remember to crop no more than 2-3 pixels from the chin, nudging the collar up if necessary, as shown in the below video:

Moreover, when you need to resize an image after cropping, make sure you constrain proportions because the face otherwise becomes too stretched or too squeezed.
