Work in Progress: Need Help

My Relictor Vindicator, complete with Demonic Possession:



I need suggestions. I want to use the whole 'golden chains & spell books' theme to represent its a bound demon. What should I do with the chains? Wrap them around the legs? Bind them so that the thing's legs are hobbled? (it is a tracked vehicle, after all, and not a walker) Or just wrap some chains around each individual leg and attach a book to one end? Or put the chain around the main vehicle somehow?

Any help is most appreciated.

(Oh, and what do people think?)
