I'll say it because no one else will.
You're acting like one of the people we all bash, Irock. You have something you like, and a bunch of people tell you it would look better a different way. You get super-sarcastic, then you say 'fuck you guys, it's staying'
I looked at a few screens, and I saw that the colors in Megaman 6 in the level you were talking about were much brighter, which is why the flat black worked there better than it works in your game, where the colors are pastel.
So, to make it mesh better, your two best bets would be to change the black to a lighter color, or make the color more vibrant.
