As described before, I built the cart completely out of plasticard. The wheels are from a Scaven vehicle. I have added some nurgle rot with green stuff around the cart. I wanted some, but not too much. Like the fiction for CoC says, the town's people welcome in the Carnival only to realize their true intentions too late.
I hope you like. Cart has been primed along with the whole warband. So it is all ready for some paint. Cheers for now.
