-shares many similar features with her sister Celestia, the most obvious being her nebula mane and tail
-her coat fades into a dark blue around her legs/underbelly and is a lighter blue around her back and neck
-body is shorter and stockier than Celestia
-wings are owl shaped with hooked claws
-large bat like ears
-her jewelry/tiara are a bright silver metal
-horn shape is shorter and slightly curved
-both Celestia and Luna have the same purple eye color
-scars on her neck and shoulder from her time as Nightmare Moon

-in my version, Celestia and Luna have the same mother but different fathers, which is why they look so different
