Don't put layer effects on your render. Use solid fonts, not grunge fonts. I would advise not using text only because if not done correctly it can actually make the piece look worse. In most cases I would definitely not make the text quite as big as you did here. I would try and add a few more effects in there and try and focus more on an atmosphere of elements rather than a background and a render. Looking up some tutorials in the tutorials section or on google would help for sure.
