Themed Character Design: 1980s Japan

Here is our second character assignment for second semester.We had to choose a theme no matter which time period or country, and design 4 characters: the hero, the love interest, the villain, and the comic relief.

So my theme was the 1980s in Osaka, Japan.

Overall, I knew what I wanted to do for this assignment, but I actually struggled a lot during the process... Many parts could have been better, but I ran out of time way too much, so this is final... for now.
Hope I could have time to do a retouch on these drawings or even just develop a complete costume color palette for them later, then that would be great. =)
