Having Toyguru's name credited for the story still feels me with a lot of doubt even if Seeley is actually doing the script.
Toyguru has proven to be a 'his way or the highway' sort of guy so I seriously doubt Tim Seeley to have much freedom to write specially when dealing with Toyguru's already F'up 'universe'.
I agree, he is very toy accurate but much of the goofiness is now gone due to those subtle changes you mentioned including a more proportionate head to body ratio. Those subtle things do make a big difference and the figure does look much better.
But why does he have clamp Champ's weapon?
