Ok, few things. 1. The face looks very menacing, I like how emotionless it looks. 2. I like how you’ve done the thigh armour, it add continuity from the arms, considering there’s no similar leg item to those gloves. 3. Not sure that the boots fit the overall style of the rest of the costume (the items shading is different and the line art is a different style), but it isn’t that big of a problem to detract from the rest of the design. 4. I can’t say I like the cape, it looks messy. I understand what you were going for, but having the cape you masked on to not have an outline makes the masked cape look weirdly broken, especially on the green version. Plus obviously you don’t have an upper outline for the sides of the cape up near the arms. But overall, good design.
