Auld Lang Syne [guitar arrangement]

After I posted my my 3-day-old Greensleeves arrangement last weekend, my dad texted me his approval and said I should do Auld Lange Syne too. So here's yet another 3-day holiday song arrangement effort for you. Unlike my Greensleeves arrangement, I did not look up any chords but just tried to wing it. Not sure if the song is supposed to have a Dm7 in there (well, a G#m7 really since I'm tuned down so low) but it's the only thing that sounded right.
