@loketi, these aren't really good enough to add to the megapack just yet. They are stretched, are cropped too far from the collar and the top of the head, and have hardly any hair detail at all. 

It's best if you upload the original sources without the background removed so that you can be dealt with by the community 👍

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.

@loketi, I've already explained why these are being rejected. Uploading them again will lead to exactly the same outcome 😕

it's my first time , sorry 

No worries, just upload the original source images without the background removed and the community will take care of them 😉
