For shiggles try covering up the left and right sides of the second pic alternatively. First I made it symmetrical like this
Then a dude on facebook dared me to "break symmetry" which is a thing in digital sculpting where the symmetry mode mirrors what you do on one side of the plane so it's half the work to make a face but totally symmetrical faces look just fucking wrong. Uncanney valley kinda shit so once the bulk of the work is done you turn off symmetry mode and work on making each side just a bit different. You can moles and scars and just generally fiddle about with shit so it looks more natural.
So I decided to practice expressions but I had two in mind - "Goblin has no requirement for the bullshit you offer" and "Goblin regrets choices he made in life that brought shame on himself and the horde". Couldn't make up my mind which to do so I decided to try half of each and see what happened.
First pic was just slightly rotated in favour of the sad side. Second one is pretty much straight-on. So it turned out that rotating the head gives me emotional volume control for the final shot. Like a crossfade from mean to sad. I kinda like the juxtaposition so I framed it straight on.
