I keep saying I love design challenges, and the universe decides to test my creativity!
Viisaus is too awesome a bot not to have his own look. So I rolled up my sleeves and got to work! I kept your specific traits: Autobot-blue eyes, belt, bolo tie, kneepads, vest, and threw in some old-time clerk and grandfather. I think he looks awesome but the real question is: does he look like Viisaus?
Ok... moment of truth... *holds up picture and cowers behind it*
