I re-did the entire set of skins, giving each glukkon a bit more personality to differentiate them from Molluck, especially the green one, so I did a little more tweaking in Photoshop. And speaking of green, I re-coloured the Abe skin and removed the stitches, for that one scene where you see 5 mudokon slaves pulling levers by a conveyor.
Now that we have a complete set of skins, I'll list them here so that they can all be found in one place:
