Headless horseman armature

I made a simple armature for the horse for my headless horseman model however it wasn't strong enough after bolting its rear feet into my chipboard so I had to re do my armature , I'm glad this happened as my new armature is much stronger . I've started packing it out with tinfoil and you can almost see that it's a horse rearing on its back legs , he needs a lot more fat so more pictures to come.
