These are two illustration that were done for my High Vision Marketing and Pitch Illustration class this past semester at TAD (The Art Department). They were assignments and not part of the official canon of artwork for those franchises.
The first image was made for the Magic The Gathering trading card game. The idea was to convey the basic essence of the character. I chose to do the Pyromancer.

The second image was made for the action-roleplaying game Diablo III. The idea was to convey an epic battle taking place between 1 of the 5 selectable heroes and a horde of Diablo's minions. As I am sure most of you can tell, I chose the Monk.
