Here are some concept sketches that I did for the Merlin story. I thought it would be cool to do a non-traditional take on Merlin (visually speaking). In comics, books and movies, Merlin has always looked fairly the same. I didn't want Merlin to have a long beard and act old and feeble. I made him look slightly more rugged and drew him to look middle-aged (or slightly older). Instead of a long pointy hat, I have him a simple hooded cloak. Even though it's different, I like it.
