I myself am underwhelmed by those. They to me are too small. They should have stuck to the the original sizes or better yet make them several inches taller than those.
For me in most cases bigger is better. That is part of the reason why I got an MPP10 Optimus Prime by Weijing. This is another example of why I think third party is better three quarters of the time. I don't own an original Chromedome but I would take it over the new one there. The very best to me of Chromedome would be Make Toys Cupola. One thing I will say though in regards to updates to the Headmasters would have to be that Fort Max looks **** badass
I prefer the looks of the original ones city mode better but robot mode looks better to me.
And in regards to Chromedome and his fellow Headmaster companions the articulation and other things about them are nice like the head sculpts. And who knows maybe there will be oversize K.O.'s of them eventually to satisfy people like me who like bigger scale Transformers.
