I actually like that they are a bit different than the original Bandai versions. Makes it better for me to be able to have both the vintage ones in my collection, and still pick up these guys. Plus, I always really like to see new vintage-style sculpts rather than simple repros, adds a lot of originality, while still staying true to the feel of the original toys. I think while this may seem like a simple concept and 'easy' technique, it is actually one that is incredibly difficult to achieve, and only the best of the modern sofubi makers have mastered it.
