So this is my first tab here on Ultimate Guitar :P
I've improved tabs which are already done here for Alexander's Rybak "Into a fantasy" 
from HTTYD2 OST
I tried to play with this version:
http://tabs.ultimate-guitar.com/a/alexander_rybak/into_a_fantasy_ver2_crd.htm
But it doesn't fit and here's my version (it's only melody):

If you need help with tempo, watch original music video on youtube:

make it sound much better)
