I’ve kinda never wanted to return to the chain rig but when I found out how to use IK constraint I kinda returned to it and wanted to test how it will turn out and yeah
Feedback on Improvements would be good (and yes I know that the chain should move faster a little bit)
I really like the way it looks The only thing That I see that you should fix is it’s speed just as you said! 
Its true. And for the fact that the chain reminds me of Scorpion from the game Mortal Kombat 11, lol
This looks really cool!
It kind of reminds me of Doctor Octopuses’s arms haha
