Interesting idea.
Good use of C4D's, but try to only use galaxy stocks as areas of explosion.
Around the white car and the text aren't totally necessary.
Also work on creating a focal.
I would crop it to where the red car on the left is gone, and the top of the gray car in front is visible only.
Then you're on your way to creating a focal.
You don't want too much negative space distracting from it.
KIU.
