Hey Pepper. You have done a great job with this effect. It will stand just fine on it's own as it is.
It doesn't read 'broken glass text' as it does 'stone text breaks glass'.
My only critique would be that you should move the subject (text) a bit closer to the foreground, move it off center or cant it slightly, which would lessen the background. Centered, the effect looks controlled and far less dramatic and chaotic.
The BG is a bit uniform. The text breaking through a glass window........
......like this......
.........could really assist in the illusion.
BUT.........as I said, I think what you have done is a great job and I only offer my opinions as suggestions for similar future projects.
