Looks a bit gloomy... But that might just be me, as prefer overly colourful things.
If you're looking to keep that "badass" philosophy while keeping this wing of envorinment, may I suggest using neon green auras or electric blue? You know, so it would look like the glow of the master emerald or chaos emerald ^^ (Best thing to me is are electric red and blues). Although I could see that, if not applied well, it would turn out to be like a generic page...
Anyway, from what I see, you seem to have nice design talents. May to keep in mind my suggestion or not, I'm looking forward to the final product. =P
