Loving your work @rfreixo - keep it up

Some small suggestions to keep improving your cuts:
a) When the source image is slanting slightly to one side (like this one), it's best to rotate the source to have it as upright as possible. For example, in this case 3-4 degrees anti-clockwise should be enough. The way I estimate is that the top of the ears are in roughly a straight-line It looks much better in-game, I tend to find
b) Care should be taken to avoid the chicken-neck effect and so all cuts should include a little bit of collar. At the same time, the ideal cut only contains 2-3 pixels beneath the chin. Since in sources like this one, the person in the image may have a longer neck than usual, this would be quite difficult to achieve naturally. This video & this post display a simple technique of how to cut close to the chin and still display a bit of the collar, essentially by nudging the collar the necessary pixels upwards
c) There is a small amount of snow around the head. Similar to point a, this is quite evident in-game, particularly on a dark skin. This short and easy-to-understand video shows a good method of how to quickly spot and clean snow. No more than 5-10 seconds' work, really, but the benefits are quite evident in-game

Thanks mons, I'll keep trying to improve!
