The metal looks good. I'm not exactly sure what you're going for with the costume but it looks like a 90s superhero; using a gun, odd mix of sexy, punky and practical clothes, pointed shoulderpads that look vaguely like armor but don't provide sufficient protection, lots of side details that scatter your attention and would be hard to draw repeatedly (hence why the style died out) - put a human in this outfit and she'd fit right in with Image Comics.
