So while I wait for Civilization: Beyond Earth to download, I decided to use some of my short time not working to post a bunch of these concepts.
So Arsenal was easy, I just was going to update the cannon and match the kits. The cannon is pieced together from the current cannon, the Blue Jackets' cannon, and my concept for Charleston in the US Soccer 2030 project.
The uniforms match the typical red with white sleeves. I used blue as a trim, and threw in some white stripes to balance it all out. The fonts match the Puma font from the world cup, and since Arsenal is a Puma team, it seemed fitting.
