This is a forum, not a live chat. People do sleep occasionally and you cannot expect answers within half an hour. With regards to your clip, I wouldn't use the waves as a matte, but rather as a displacement map. Blur them slightly in your pre-comp, use the displacement map effect on your footage referencing the waves as an input, dial in suitable values. That doesn't mean you couldn't use it as a matte, also, but a little experimentation is required. And if you don't mind: Go a little more subtly on your effects. Rather than overcranking your colors on the effects, colkor correct the base footage to improve contrast, e.g. desaturate the colors in the floor and furniture or change the boy's red Tee to a less similar color from your lightning and light beams. It's all about luring the eye into seeing what you want it to see...

I doubt you will get people throwing you ideas. After all, experimenting on your own is half the fun. Additionally, nobody will give away their best kept secrets that easily. Essentailyl you are also asking the wrong question: The question is not whether you can use and create 1000 different effects, but rather whether you can develop your own visual and artistic style. In the end, it doesn't matter whether you fry people with lightnings or laser beams, it matters that the execution of the effects is spot on and you have some work ahead of you there. As I already wrote, practice color correction to improve your results. Use the same effects in different scenarios and use variations of them, then learn how to refine them, e.g. in case of your lasers by adding smoke, debris, particles or again using color correction methods to give the illusion of charred trees, furniture or burn marks on the walls....
