I uploaded just the background of this earlier. Hope people enjoy this one, as I always like making manipulations that involve outer space.
My theory on lighting in outer space is that light comes from everywhere, which is why the horse isn't super dark even though it's strongly back lit. Also, the hooves are sort of pulling little aurora's in space, but it's kind of hard to tell in this with the background being equally as aurora filled.Credits:
Most of the space images came from various Cosmos packs provided by funerium via the group Resurgere; there are over 8 different space images in this.
