This is just my two cents but doesn't Revan's mask have more darker hues? I love what you've done with the helmet (I agree that it makes more sense to be a helmet rather than a mask since Mandolorians are more bucket heads than maskers) and I like the detail but it seems like too much of the rustic red. I would love to see more black (or better yet, deep scorching around the areas that should be more of a blackish color)!
Keep up the good job man! I really like it so far!
