Create a portrait of a male human character for a D&D 5e character sheet, named "Ashes". He is a first-level rogue. The character is a survivor of a terrible fire, resulting in severe burns covering his face, neck and part of his shoulders. His skin is scarred, with patches of blackened and leathery texture. One of his eyes is milky or closed due to the burn. He wears a thick, roughly made leather mask that covers most of his face, leaving only one eye visible. His expression is menacing, full of pain and anger, as if he is constantly glaring at the world. He has heavy, roughly made leather shoulder pads with metal studs and spikes. His clothing consists of dark, rough and worn fabrics. He is looking straight at the viewer. The background should be simple and dark, so that the focus is on the character. The overall tone should be dark, gritty and threatening, conveying his inner turmoil and physical suffering. The image should be suitable for a character sheet. Make it a digital art, medium detailed, and with a dark and moody color palette.
