I really like taking my sketches to SFFC; on Sunday I played around with doing the Futurama characters as Manga. If I get really energetic, I want to do a parody of Futurama as Escaflowne characters - one of the ladies practically is Leela.
It was the "acid" years so color was very much in demand. The more eyepopping the colors were, the better you "tripped". So everything was overdone in colors. Concerts always had colorful lights flashing all around. You captured that decade quite well. I got a real feel of the 70s from it. Well done.
