picture I working on, concept for the horns mainly.

"made of some kind of energy the horns sit slightly above the head, made from light they are insubstantial, the strength of their glow can indicate awareness, and emotions, though can be manipulated slightly, the only time they do not glow is if the creature dies or passes out in some form aside from sleeping.

anger and happyness make bighter, sadness or tiredness make it dimer blah blah.
