In fact, I truly enjoy his design. He appears feeble and unimposing, which contrasts perfectly with his powers as a badass with surprising speed and mental strength. Although it is not particularly inventive, Ed appears to look the way he should have always looked. In five, he was too heavy. In number six, he has lost weight and appears exhausted, as if the psychic power is failing to care for him. I believe that dressing more casually works well with him.
However, I'm intrigued in seeing what his movelists will be. It will be interesting to see how his Modern and Classic division develops, given that his inputs were already simpler.
