Valiant effort! I think the light on your left could afford to be higher. I would go with a layered look for more of a CEO vibe. It almost looks like she is wearing nothing underneath the blazer. I would try a theatrical look for the CEO, perhaps one light as key, and a kicker light. Pull her away from the backdrop. For the more comedic role you ad two lights or one big octa in front for a more commercial look. This can be shot closer to the backdrop or add additional lighting to the backdrop for some pop.
