I think both of the sprites are really good, but both communicate something different. I feel like the one on the right is great for a simple npc character and really conveys the style of a warrior, while the one on the left makes her pop out way more, making it known that she is somebody important. While I think I'd rather go with the one on the right, maybe you could add something into her attire to make her stand out a bit more. Perhaps the same purple but on a smaller part of the uniform? Maybe the shoulder pad?
