Woah, this is way cool of you. Thank you for doing this! I'm actually happy with my current thumbnail, but I have one I would like to use in the future with my main character on it.
His name is Mel (short for Meltros). He's 25 has an angry expression and tired eyes, has dark brown medium length hair that is combed back, and a short single horn on his forehead. He has heterochromatic eyes, the right amber and the left black.
A knight in a holy order, wearing silver armor with a light blue sleeveless surcoat, it has an embroidered white star on the chest.
His job includes patrolling the city he stays in, going from village to village carrying out exterminations of beasts, and keeping order within the borders of the country he is assigned too.
The world he lives in has experienced many choatic times and now there is a second moon bigger than the first, people are worried it's a god coming to smite them for their sins.
Edit: Forgot something, his skin is also a light tan.
