I decided to interpret the prompt as embracing the meaning and power of ones cutie mark in this drawing. Luna’s conquering of her guilt and forgiving herself for past mistakes was a really strong message for me personally, and being able to accept the kindness of her friends were both powerful moments. Once she forgave herself, she was able to accept the darkness inside of her and embrace her power as the Princess of the Night!
 
Even though we all have darkness within us, accepting it and forgiving ourselves for those faults will help us achieve our greatest feats. Thank you for the lesson Luna, and what a fun drawing!
