In flamenco, rythms (las compas) are quiet important. I think it's important for you to listen at the beginning the different falsetas play by flamenco players (los tocaores) in order to understand and learn the different rythms characteristics to the soleares, bulerias, tarrantas,farruca,granainas,alegrias...
You also must developp some particular techniques like rasgueados three and five strokes,alzapua, marote, tremolos...It will be easier for you to learn flamenco if you are a strong classical or fingerstyle technique...
