In my eyes they weren't 3D, they were just placed on the wall.
You should definitely work on your effects. That red overlay was quite annoying.
The music was quite annoying as well but that's a matter of music taste so it's alright if you like it. You should sync it up a bit more though.
Also work on your smooths! Bring a more cinematic feel into it.
Other than that, probably better than my first tries, haha.
