What not to do in a superhero game/movie/cartoon? Advertise a popular villain quite prominently, even dedicating an entire CGI trailer, than make him the second boss battle, and remove him from the story entirely.
Your line work is pretty awesome, I like the way the action takes place in their poses. I also like the color work by Rodendron. if you are interested, check out my new comic book universe in development, we can use talent like yours. doombox-comics.deviantart.com/
