Diluc: Flicker of Doubt

No idea how I finished this, I am close to offing myself these days. XD
Wish I had more guts and was a little more selfish, ANYWAY about the artwork, I feel like a lot of people are 'sad' when they get Diluc instead of xx special 5 star.

I feel kind of bad for that, so this is him, with a flicker of doubt in his face. For whom does he still fight? Is himself still a valid reason?
