Well what does Rodger look like?
Height, build, hair, skin colour, face fungus, habitual expression, background in case it inspires a variation, primary specialization?
If I go purely on your vocal mannerisms, I might imagine a young, clean shaven, wiry, pale skinned, redhead. But it’s your character 🙂
I usually do a spacesuit variant and a dress uniform.
Where did you grow up? Gravity, occupation, hobbies? Anything might help.
Cheers
