Cheers for your thoughts guys its much appreciated. I will try and make the limbs look more natural by using the transpose tool in zbrush to make them less rigid. I will also try and get the proportions better by increasing the calf length as suggested.
Thanks for the comment on the portfolio Arran. Have to say the office renders look absolutely stunning and your jacob marley project is looking like it is gonna equal if not better it.

As said before I am gonna come back to this fresh next week so will have an update then.

Thanks for the tips, and keep up the good work guys.
