@SergioBv, I'm afraid your cut contained a fair amount of snow around the head. In the thread I linked to you earlier this morning, there's a link to a video demonstrating a quick and easy technique on how to spot and remove this snow. I can't remember what technique you're using, but I would suggest using remove.bg, which gives you a much cleaner cut with much less snow.
Hello @mons
I use Photoshop (Refine Edge...). I've been testing remove.bg, and yes, the cut is fast and good. I didn't know this web. Thanks for your patience.
