Here's week 4! I wanted to use this as an opportunity to try modelling a bit of armour from spheres/primitives in Zbrush without using poly modelling (which is how I'd normally do it) so I ended up pushing it a little and spending an extra few hours. The theme (set by the Outgang Studio Discord challenge) was scarred warrior. I wanted to do a woman who was strong and capable.
Unfortunately Zbrush crashed later in the process so I don't have a full video for this. I'll see what I can salvage later.
