@Ttggfr Be careful with pre-cut sources like these, it had snow/background artefacts that need to be removed. Just cropping and rotating sources like this isn't enough.
I increased the contrast just to demonstrate, in case the snow wasn't visible:

To add to what @weeniehutjr said, I suggest that for pre-cut sources like this one, you put it through remove.bg, which will clean those artefacts and snow and save you the edit of doing it yourself
