Thanks lostclimate. I agree the normal mapping isn't doing much for it in the shots although running in engine it looks much stronger, still im not happy with it as its not baked, just a quick pass with the Nvidia plugins.

Once I've got it rigged (couple of hours) I will be revisiting the mesh again. Im still not convinced that his 'butt' area is going to be sufficient for good animation.

Thanks for the pointers
