Everyone who's dismissing this because it imitates the style of another artist (as if that was a hard technical limitation rather than a specific prompt) or lacks the je nais se quoi of "real" art is missing the point. No one would ever hire a concept artist capable of doing this when they can hire someone for a fraction of the salary to write prompts that return acceptable results in a fraction of the time.
