hey, so i've been trying to figure out the strumming patterns to this song: http://www.youtube.com/watch?v=eetIgGXH6DA

I came up with a version that sounds okay-ish but still isn't right when I compare it to the actual song. i know this isn't a tab request, but if anyone could help me out figure out the way he plays it in the song, i'd really appreciate it! thanks in advance!

(already have the chords, just need the patterns)
