Simplify. You know what you're talking about because you're presenting, but your audience might not. Make it as easily digestible for them as possible and be as visual as you can (diagrams, charts, etc) so everybody understands.
Yep I'm in Finance so there's going to be a lot charts. My issue stems from losing concentration whenever I look back at the powerpoint projection. That and an engaging introduction seems to be my biggest areas of improvement.
