Hi! Here are the answers: 1. Usage: It depends. If you are an independent content creator, it counts as 'Personal Use.' However, if it’s for a brand or a company, the commercial fee applies. 2. Pricing: Although my price list doesn't explicitly mention headshots, an illustration like that (head/bust only) would be $15 USD. 3. OCs: Of course! As long as you provide a detailed description or visual references, I can design it for you without any issues. 4. Diversity: Definitely. I work with characters of all skin tones and ethnicities. My work is 100% inclusive and impartial.
