The only editing flaw I saw

The only editing flaw I saw was the guy running back to get the camera, that could have been cut out. And since your using Kdenlive, I can see your computer is running a Linux Operating system. Us folks in the Linux world do not have access to any program like after effects, but with GIMP, we can do wonders

And note to Paulears, if you have never investigated Kdenlive, it is a NLE Video Editing Platform that ranks right up there with Magic (Vegas) 12 or better.
