Ultimate Black: Ideas generation and rough sketches

 Here are some sketches I have made to get started with the character designs and trying out new ways to create my existing characters, I have currently drawn these character digitally and and adjusted what I think are best suited for these character designs. However, the last design will remain mostly the same since I have been drawing that for quite some.
