Well i used some tuts and at the time already sorta of had a style (not that good ) and started to mix in diffrent layers and blending e.g.: my noob style :P : Copy Render Fliter>Blur>Motion blur. That was bg and all i did was brush and blend. New style: Smudging, Filters, C4D's, Better text. So look at tuts and combine thats my advice.
