Maybe I need more practice, but this is giving me a lot of trouble... is there any special technique to it?

you could do it all downstrokes and it'd be easy but your arm would get tired fast so your best bet is alternate pick it. also why dont you transpose the d string notes onto the a string so that its easier to play

Economy picking.

Pick each note on the low E string with a downstroke and the notes on the A and D strings with an upstroke.
