In Princess Tutu, one of the heart shards is the feeling of fear, yes?
Can you imagine what that would be like? Mortal fear. Terrifying horror, being felt for the first time. Not just, "Ah, you scared me!" It was looking the devil in the eye. The poor prince must've felt like running and dying at the same time.
In the anime, he has such limited expressions... And such a whimpy scream. So I decided to draw what I thought Mytho should've looked like when he first got back the shard of fear.
Don't ask me why Fakir's naked. He looks better like that anyways. ^_~
