I dont have a soundtrack really and i honestly dont listen so much to music when I draw (i get to easily distracted lol) but there is one song from Ellie Goulding - Only You, that actually was the inspiration for a very important scene for my comic that is coming much later, i like to sometimes imagine my storys as an animatic and I could just see the scene playing out infront of me to this song
But if I had a soundtrack I think it would have something with the same feeling "of Monsters and Men"s music maybe
