When I create a creature or character I require several items beforehand. The first thing is an idea. Seccond is a lot of references. Third is the medium by which i would create the artwork. I like to work in oil based clays such as Sculpy clay or monster clay. The difference between the two is that Scuylpy can be put into an oven and baked till its hard. Monster Clay on the other hand gets soft when its hot and can even be melted. I like to use Monster clay for projects that I will be making molds of and then casting resin prototypes or finalized pieces to be painted.
