A song of ice and fire

Guess from the title which fandom, I'm refering to.. :b
I find myself drawn into the amazing world of George R. R. Martin.. Some of the best books I've ever read..
So far I've only read the first two books, so I'm still ignorant and don't yet know much of the story (please no spoilers here.. )

I have a weak feeling that the title may be refering to Jon Snow (ice) and Daenerys Targaryen (fire), so I drew them with their elements..
Also I really like these two characters, and wanted to do a portrait of both..
