My basic idea with Primus was to streamline the design from Cybertron, because the earth looks like a smooth round ball from space, but close up its full of numerous different surfaces. I keep telling my self you don't need legs in space, but I can't find myself to draw space mermaid bodies.
With Unicron I decided to go for the gusto. Completely drastic alteration to emphasize the fact that he's an evil son of a gun. I tried sticking to my "no legs in space" mantra that I set up, but I'm thinking of redesigning him Anyone who wants to try their hand at coloring either of these two, be my guest.
