Analyzing Claire Hummel's work on characters like the Luteces, Heli Salomaa remarked that her work as an assigned costume concept artist was further from fashion designer’s than costume designer’s position, but the full potential of utilizing costume narration was insufficient without further personality content and deeper analysis of the characters. To Salomaa, designing aspects of a historical period for any medium requires thorough familiarization with the collection of historical references, as it adds legitimacy and depth to the character, as costume history offers an endless selection of various authentic styles and guides the consistency of the art style.
