A few tips:
Keep it simple, almost vector-like. Gradients are so 2000. See mitsuse's 'flat' openbox theme for what i mean. Keep the system lightweight not only physically, but also visually. The orange is nice, ditch the brown (seriously.). I say, get a color that matches and compliments the orange. Teal is a pretty obvious choice, but it will also get you negative publicity for jumping the teal/orange fad that is so ever-present in the movie industry.
Also, seriously don't try doing some douche-cool things like the spider-web designs I see you've been experimenting with. You'll come off as stuck in the early 2000s (I can't stress that enough).
You can keep the spider, change it up, maybe.
