Get a better render ( the current one is low quality ).
Try to blend the render in the background so it doesn't look like you just slapped a render on a random background.
The text is too small and can't be seen. Make it bigger and put it next to the render, not on it.
You should try and do something with the render, add effects to it, c4d's, brushes, anything, it looks too plain right now.
And add a 1px black border.
