1ST THING FIRST.
TEXT: I KNOW ITS HARD.
It's in probably the worst position possible and the worst style of text, try and make the text a bit smaller and maybe ina different position, a position where it doesn't seem far away from the focal yet not too close.
Render: I think you've blurred the render too much because it honestly looks like low quality to me. I see you did try and create depth but it hasn't worked out very well. Also the render isn't well blended in to the background, try a bit of smudging with the render and try to make it one with the background.
Background: Simple but not too bad. It needs more VARIETY. Try use some c4d's and not just the basic smudging or distortion.
One last thing, LIGHTING.
The lighting IMHO is not how it should be, it disturbs me too much and there's too much lighting. Maybe another place or lower the opacity of the lighting.
