I joined another swap with my friends at Acetsy: ACEO Etsy Street Team. The theme was Halloween. I got my idea from the Grim Reaper but with a small twist. For the scull I used one of the Crystal Skulls (aliens). I started with a card painted black. The skull was created with a light wash of white acrylic to a more intense white. I highlighted some areas with iridescent white.
My steps are below from my thumbnail on a scrap of paper to the finished product.
