I totally get what you're saying, and it is your illustration and your perception of the character that you created on paper. I myself am a stickler for those things when I am creating renderings of preexisting characters but that's my opinion and certainly not a rule. I love the piece don't get me wrong I'm just a detail fanatic and also a Genji main, I'm obsessed with him lol (and that skin is my favorite). Also for a bit of clarification Hanzo is the Samurai and Genji is Nenpo/Ninjitsu. Samurai also use both hands on a sword, as does Genji when using his Ultimate. Except for the famous Miyamoto Musashi. Anyways, enough of the rant. You've sparked my interest to draw Genji with this skin.
Again, great job and keep it up!
