Yeah, the biggest problem is the only reference I have is the scanlations, and he's solid black all over, so I was winging it the whole time. I have to wait until the anime stops with the neverending filler arcs and gets back on-track before I can have a better reference. Goodness only knows when that'll happen.
Yeah. I understand sometimes there isn't good enough reference. It makes doing artwork very difficult. Still, it would have helped to imagine what it might look like instead of making his face so flat. Just something to keep in mind in the future.
