Really nice. I like it alot. The only thing I would change is adding an open space in the helmet for their silver mouths. But that is more just a personal thing, I want to see them talking with their silver faces instead of static mouths. Really cool. I too hope they put more into the reboot.
I always thought about how would it be if the Rangers would taken seriously... Using armor instead of tighs. But my ideas were awlays kind of medieval-magic style. I really like the Mass Effect feeling of your redesign because the Rangers always had that high-tech gadgets. Congrats!
In a way I hope they do get rebooted. But only if they make the Power Rangers a little darker for older fans but not too much for new fans and I hope they redesigning the suit's as will. I think looking on this website and character molds like yours would be a good place to start for an idea's of an new design's.
But if they copay too much we could hear people saying "Hay they steal our design!" all over the web. But this is wishful thinking for I think they still make bot louds of money gust the way the Power Rangers are right now.
But still great work, I hope you do redesign's for all of the Power Rangers. (You know Red, Blue, Green, Etc.)
