Two animators of Bleach: Sennen Kessen-hen, Suzuhana Yuuta and Chen post extra artworks on their Twitter accounts. Although those are literally equal to the official art, they should be not tagged as such, but rather official style, animators create extras in their free time and don't cover all anime episodes.
There can be more artists included should they be found.
Artworks should be sorted by anime episodes when possible.
