Large Print Concept

For a project I’m doing in photoshop, I will being creating a large poster-like image that will consists of multiple pictures of the video games I play. I cannot draw my visual idea (because I’m bad at drawing) but I can tell you that the images are all war based games from all eras, so I will be making an image based on the progression of warfare, from medieval times with swords and shields, to futuristic warfare with things such as jetpacks.
