I think I've possibly seen the tutorial for this? You've put a nice twist on it though which is cool

The vector art in the background would probably benefit from having a bit more form as opposed to flat shapes on the canvas... make it appear as if they're also popping out as the text is.
And the bright sparkles on the text should also really match with the lighting, as currently there are sections where the type is in shadow yet somehow a small bright flare is there also.
May I ask what 3D rendering program you are using? (I'm assuming you're using an external one, and then importing the shapes in to Photoshop).
