2D CHARACTER If I have a preference for creating concepts it has to be a preference for monsters and creatures. Second to that are characters. I find it incredibly difficult to decide where to put my creations as many creatures are characters and vice versa. I generally use the term for something that has at least some human characteristics and isn't wholly alien.
I find inspiration all over the place for my concepts. I am an avid movie goer and spend hours looking at my book collection for nuggets of gold to fire up my imagination.
