I am working on a concept art for a Ace Combat fan based Flight Arcade Game called Ace Bloxia: Skies of Hope. It takes place in robloxia where you fly as a Ace pilot saving the world from deranged rebels to invading countries at war with other nations. Aircraft can range from conventional real life jets or fictional fighters, all of this is made by my art.
Well, yea, if you make a 3d scene in your game, apply all types of RTX and stuff, screenshot it, maybe add some filters like blur, then bam, youve got a thumbnail for your game.
