Goblins revisited

I added a few changes and I think that overall it's an improvement. I basically repainted the wooden platforms using darker browns, added some black pigment to the stones, repainted the ugly boils using basic skin tone, got rid of the red around the eyes and chose a softer, warmer color for the base rim.

I'll start preparing the rest during the weekend. Can't wait to get started on Thorin's company!
