One of my friends had the Double Dragon cartridge for the NES and I remember playing the game with him when I was a kid. In the original arcade game, the two characters were nearly identical on the screen except for the hair and pants color. Over the course of the franchise, their looks evolved as technology progressed. For my customs, I tried to incorporate elements from a few different games while keeping them steeped in '80s looks. Since they are twin brothers, I used the same recipe for both.
