This was the first ref-sheet that was ever made for Dao, maybe 11 or 12 years ago? It's... been long enough ago that I don't fully remember when that was. Crazy to think that his wings used to be grey(ish) in coloration. Looking back at it now, it's funny for me to see how little the design has changed. Probably because, admittedly, it's a very basic design concept.
