Just 3 years later, I thought I should update this thread!
Here's a model I've been working on and off for a while. It's a collaboration with an insanely talented 2d artist called James Harvey (www.stopjamesharvey.com) to take one of his characters into 3d. As she's progressed she's moved away from the original design to some extent but I'm still fairly happy with how she turned out.
Everything was created from scratch in ZBrush with the exception of her coat, which I made in Marvellous Designer (then retopologised, UV'd and detailed/tweaked in ZBrush) and her gun which I modelled in 3ds Max.
Final render was done in 3ds Max using V-Ray with some post processing in Photoshop.
