@Miqdam Ghani no problem glad to be able to help! In terms of shape design, I’d say maybe the chest plate on the hero class could be exaggerated to push the shape and set it apart from the body, like adding an angle at the side as it slopes down to meet the torso. The arm plates could be brought out a little especially at the sides, just to make them distinguishable. The shape could follow the dragons body; it’s thicker at the top and becomes more narrow at the bottom. Hope that makes sense, if it doesn’t I can draw out what I mean but this could also just be a stylistic choice. I think your shapes are already really good, can easily tell from silhouette alone which character is which.
