This is an illustration for Fantasy Flight Games collectible card game named A Game of Thrones, which is based on the world of best-selling author George R.R. Martin's A Song of Ice & Fire. This was made for a special plot card.
The characters are Cersei and Jaime.
Illustrations for card games like this always have short deadlines, and are supposed to be viewed on a smaller scale than here.
Jaime's raised eyebrow says it all. I like the way you didn't show Jaime's right arm, the viewer of this image can wonder if he has still got his hand or not - in any case he uses the left hand to stop Cersei. Beautiful image, and very intriguing.
