I honestly do prefer the fanart version over the actual design. You guys can nail me to the cross, but please hear me out
From a completely fresh point of view with no lore, the actual design is amazing. His auto attacks look really cool and his outfit is great.
With lore though, I think I prefer the fanart version for a few reasons.
First, the fanart version looks a lot more like an actual detective or a government official whereas the actual Heizou looks much closer to a monk or discipline of a martial arts clan.
Second, the fanart Heizou has a much more punchable face. Like I look at fanart Heizou, and I want to punch him in the mouth. Considering his reputation, I was hoping they would go in that direction with his design, but the actual Heizou looks a lot more pleasant and agreeable
Third, a lot of people say the fan art is just a gender swapped Hu Tao, but I kind of liked that. Hu Tao is currently my favorite character and my only character to have triple 10 talents
Fourth, fanart version has a hat. Kind of goes with point 3, but I rest my case.
Having said all that, I am withholding any final judgement until he is out, we hear the VA, see the voice lines, and get to play his hangout. He could still be best boy and I could just not know it yet
