I have decided that the relationship between the hero and villain characters could be interesting if it is hinted that it is almost a romance. I have decided to make the villain character female; and also taller and slightly older looking than the hero character. After some initial sketches to figure out what kind of character she will be, here is a rough character design, slightly based on that of the hero.
I have also been considering possible styles for my film. There are very few films and animated films that are based around arcades but I came across the animation work of independent animator M Dot Strange. He released a film in 2007 called We Are The Strange, which is surreal and almost enduring to watch but he really succeeded in creating a vibrant arcade style that was dark, nightmarish and also very avant garde. The film almost had some gothic elements to it, here is a trailer so you know what I am getting at.
