Hello Edd! I really like your character design. I specially like number 1 and 3 but I think the most important thing is to give your character a color palette that helps show your character's personality and background. For example, number 1 makes me think that it is part of royalty or at least that it has an important role in his society because the color of his armor is gold. Number 3 gives me more villain/antagonistic vibes.
