@Cocoooooo69, kudos for giving it a go but this cut still needs a fair bit more work before being added to the megapack. The edges aren't quite smooth and it's not in the correct dimensions. Moreover, it's smaller than the current 250x cut which is clearly of superior quality.

Have a look at this thread for guidelines for cutters and video tutorials on what we expect for from our cuts.

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.

Thank you for all those informations. 

I'm just starting out, I didn't know all the criteria. I will try to do with these software.

Sorry for all the other photos that are not up to standard 

No worries, that's why I mentioned them 👍

I'll try and fix the ones you uploaded overnight, but please make sure to read and follow the guidelines available at every step from now on, including to upload packs if you have multiple images.
