@Jamzbout, I'm afraid these all have no collar and no hair details. This thread contains guidelines for what we're looking for in our cuts in terms of dimensions, snow, collars, face orientation etc. and video tutorials for each element. Please avoid using image enlarging software as the results are visibly overly sharpened, thus taking away a lot of face details.

If you want to give it another go yourself, I would recommend using remove.bg, which is a free online tool which removes the background to an excellent standard, for free and almost instantly.

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.

Do you now how to increase image resolution I've tried using Remidi but the results sometimes look weird 😔

Sometimes it's possible to find a larger version of an image by playing around with the URL, but using an image enlarger is not recommended as the output often isn't ideal, as you mention.

Good cut, but the current image is very recent and of a good quality.
