Remove.bg is not good option to cut this one,so who ever decide to do it,please don't use remove.bg,this needs to be cut in old manner as we all was doing long time ago.

If you're so demanding, perhaps you can give it a go yourself or at least give us a reason why remove.bg is particularly unsuited for this source. 

I've tried it myself and I don't think it's particularly unusable to be perfectly honest. Sure, it needs a little bit of snow removal in the upper part of the hair and some clone stamping in the top of the hair on the left, but neither are related to the use of remove.bg and more to the trickiness of the hair in the source image.

Did I ask anyone in specific to do it? No,I didn't. 

If no one do it,that's fine.I can also delete this request and forget about it.

I've tried it with remove.bg also,before all this,and hair details went bad,and cleaning up already cut image is a nightmare,and most likely you'll loose some hair details.That's the only reason I wrote a comment.

Most of new cuters using just remove.bg,without much care of hair details,white outline and cleaning up that.
