As you know the first couple are sex.. I don't know what to really say other than that. The style is a killer, if you're looking to improve it then integrate new things along with it. C4Ds, wireframes, stock effects, and just build upon the style even further. Take it to the next level.
like pink said maybe a few more elements in the effect compo also more depth, just not stacking effects but give em seperation and a 3rd plane of depth
