You're asking to make it different, but keep the things that make it the same. I can understand the frustration when hours of work are involved BUT My tuppence worth is forget it. Put it down to experience, try to use what you've learned in the process and do something of your own. You obviously can, so I would say; have a bit more faith in your own abilities, and don't think you need to copy someone elses design. One suggestion: how about flattening the skull sideways, and using it as the blade? regards peejay
