Well I didn't end up working on my Minotaur's over the [I Swear Too Much] break.
Saying that I've not been idle. I have been experimenting with the different types of Worbla the material the cosplay community use to make costume armour. This thermal plastic isn't useful for making armour at Warhammer scale but it is useful for making capes. cut a basic shape apply heat and you can bend the stuff around the model giving you a dynamic cape. applying a little greenstuff after its cooled and you can make the fine ridges can folds.
sorry its not the best image I'm taking it at work and I've not got a model to use as an example.
