These are atmospheric screenshots from a player named XOFV. For their work, they will receive the Art Emblem.
And here is what a player named XOFV has to say:
Impressive shots from action movies and beautiful scenes with mighty heroes fighting against an army of foes have always drawn my attention. These moments are fascinating, like the stories from childhood: knights slaying dragons and warriors fighting raging evil. In my opinion, screenshots and various illustrations allow you to recreate epic scenes, show your view of what's happening, and display emotions and atmosphere you're experiencing in different games. And when developers provide convenient tools to create such things, it increases your interest.
