Matte Painting VFX

In this scene, the actors are getting shot at by the flying spaceships overhead. Using stock effects I was able to show the dust/dirt hits from the gunshots. Additionally I added a fence with signs on to make the set look more unique and important. I added several effects, which, in the end didn't turn out so well, such as rain, sky replacement and a full camera track across the shot.

Ways in which I would improve this shot would be, one, add a variety of didn't dirt hits to make it look realistic. Two, add more back ground objects and maybe replacement the whole back plate on the top half with a matte painting to further extend the scene.
