Axl , it would be very hard to learn this technique if you're not familiar with classical finger picking style ... Try learning some basic pieces like Romanza & Malagena .

If you wanna practice this (I don't know it's name) technique , try getting your picking hand familiar with these patterns by playing open strings first.

T I M T I M
e-0-0-0--0-0-0-- (Triplets)

T I M R T I M R
e-0-0-0-0--0-0-0-0-

T=thumb , I=Index , M=Middle , R=Ring.

After you master these patterns , try playing scale runs and stuff like that , then try moving into adjacent strings or even try some string skipping.
I'm not very good at these stuff myself , since I rarely pick up my spanish guitar these days ... I need someone to encourage me to start Flamenco again. ;)
