My friend, Steph, introduced me to a couple of artists who's graphics were like walking into my Dragon Rider world of Ketall. They are amazing - Paul and Stephen Youll. I can't find the links to their work, but I'm sure if you Google them, they will come up. :)
I'll also make another post later tonight to announce the winner to my back-to-school giveaway. Good luck!
Be definite in your aim.
