Well done on getting publised!
So, big names;
George RR Martin of course
Brandon Sanderson is becoming big as you mentioned. You said you've read Elantris and Mistborn, but I recommend reading the Way of Kings, the first novel in his new series; The Stormlight Archive. I predict as the Stormlight Archive continues he'll get even bigger.
Philip Pullman's pretty big too, check him out
