Great job on Superman. I've never had an issue with the red trunks but it's great that you replaced them with different coloured leggings and used the darker blue to break up the costume, same way the trunks did. Really makes it pop with four colours going on. Also, y'know, giving him an actual belt. Most Supes redesigns that're basically just "We ditched the trunks" look so dull to me that it seem like they may as well have left 'em there.
I'd pay money for a comic or a cartoon with designs these great. Awesome job!
