Hmm.. if you made the background yourself, then trust me.. you should go find some on the internet for now.. and make your bg's when you feel good enough at brushes.. the text sucks.. for beginners, you can just let the text completely white colour with a 1 px stroke and some shadow to make it look more better.. thats all.. and try to blend your render.. if you dont know how to use it, then you can do it the way I do..
Filters > Blur > Gausian Blur > 4.0%
and then press Ctrl+Shift+F and set it to Hard Light.. thats the best way you can do it..!!
