Thanks for the comments guys. Yes I wasn't completely happy with it. I found the walk to be the hardest thing so far as he turns about 30 degrees to his right before walking off and I hadn't realised that this was a very difficult thing to do with this skeleton, I think it needs another bone at the bottom of the skeleton to make this look smoother and easier to animate. Well we live and learn.
