I think it is best to take huge scenery as the background of domineering snow photos, such as snow-capped mountains or hillsides, which can be used as the background to take domineering snow photos.
I think it's best to pose as a winner in the snowy mountains, which is enough to show your domineering. You can also put your hands in your pockets and keep your eyes on something. This pose is best shot from the side, with the snow scene as the background, showing your domineering.
There is also a posture that can show domineering. You'd better take a close-up when you're lying on the snow, which is also very domineering. Another is to capture the moment when you jump. Your hair may be messy at the moment of jumping, but I think it is this dynamic beauty that makes the effect more domineering.
One more thing, domineering snow photos are not necessarily full-length photos. You can also take a half-length photo. I think the effect will be good.
