I like the idea of using scale for mediator. I think right leg is a bit too heavy for this type of character.
Some questions I ask myself why designin characters:
- what is the setting, culture, place - do they need warm clothing or maybe some armor
- who is the character - profession, personality
- can someone else tell that it is this character I had in mind while looking at it
Ask yourself right questions and design should come itself. If you are stuck search for more references, maybe read something about some culture, animals, anything that comes to your mind. Look up some movies or games you are interested in and see how they create such characters.
Nice work!
