I wanted to draw (Frankenstein) Denmark seeing his reflection, but I didn't want it to be a mirror so I used ice instead, (originally I was going to use water, but decided to use ice instead, I don't know making it snowy made it more "emotional.." )
I didn't put any dialog because I want the viewers to imagine what Denmark is feeling seeing his reflection for the first time.
The thistle is the emblem of Scotland as a barefoot viking raider cried out in pain as he stood on one, alerting the Scottish army encampment that the Norse army were sneaking up on.
