First, i wanted to do Sheffield Steelers, but that's the name of the hockey team(they even use the same colors!), so then I tried the typical club names. But since Sheffield is known for it's industry, I went with Union(workers union, you know). Orange, grey, and black, with diamond plating on the crest underneath the Yorkshire Rose.
The kits are simple, I know I wanted to do an orange top with a dark grey bottom. I went with adidas, and sort of based it of some teams, but made it my own. On the clash I wanted to do as much on the uniform as i could, but not use it as the actual color of the part.
