Author's Note: Inspired by St. George and the Dragon by Jacopo Tintoretto, painted circa mid-16th century. Reference/Original here.
The style I've used here is my personal mix of fantasy alien Jim Henson-inspired elements (eg. the Princess' nose, in case you paniced there), and I emphasised the battle between the Saint and the Dragon as more emotional and intense (the torn clothes, wounds, upturned earth, the cheering crowd atop the fortress walls) than the original. I omitted the corpse from the original because I thought it looked quite random as a solitary semi-naked figure (the dragon's lunch?), so I replaced him with a damaged shield instead.
