"The cream-and-gold dragon was suckling at her right breast, the green-and-bronze at the left. Her arms cradled them close. The black-and-scarlet beast was draped across her shoulders, it's long sinuous neck coiled under her chin."
~George R R Martin, 'A Game of Thrones'
When I read this part of the book I was struck by it. It drives further the fact that she is truly the Mother of Dragons in every sense and they are that precious to her. Don't know why they didn't depict it accurately in the show. But all her hair burned off in the book too, and I just had to leave it in. You know I loves to draw me some hair.
I wanted to draw her like those medieval paintings of saints you'd see in a cathedral. Hence the moon behind her as a sort of halo.
