only parts i dislike are the "sniper sniping in a tree" 7 syllables
"Partidge in a pear tree" 6 syllables, just when i read it, it didnt sound quite right...
also, for the fifth day, you should make it in that way that the carollers do it
FIIIIIIVE GOLDEN RIIIIIINGS
edit: i suggest you sing it for us and put it up as a youtube video :3
