Thanks for all the comments guys it is much appreciated. The main problem for me at the moment is the hips area and so I am going to try and sort that out for now. I may then just set up the cape and get some renders of him in the batmobile to see how it looks.
Once I get some decent renders I will look over some more anatomy books and check out heroes and vilans. Hopefully this will allow me to make more improvements to get the anatomy more balanced.

Thanks for the help and advice guys it is much appreciated,

Leon
