His backgrounds seem fine to me, not as much detail as Kingdom or Berserk but still
I mean the recent art lol
Notice how other than not drawing backgrounds in most panels, most of the scenarios he creates are:
- Fights in the clear sky, with barely buildings in sight most of the time.
- Seiretei. Long, empty corridors of white walls with no decorations.
- Hueco Mundo. Big empty desert.
- Las Noches. Big Fortress... for cylindrical buildings with no windows or decorations, just white uninspired walls.
- Wandenreich. Same as Las Noches but with more normal-shaped buildings.
It's not that he can't draw beautiful backgrounds, it's that he thought of ways to avoid doing so.
