Which maps and locations are these operator art images from?

Seems like after doing some digging they seem to match up exactly to their appropriate locations.

Tachanka Elite 2 art

• Kafe map, 2F, Reading Room
• 

Blitz Elite 2 art

• Clubhouse map, 1F, Bar
• 

Frost Elite 2 art

• Yacht map, unknown
• No room in Yacht has a pillar with two barricaded windows to either side. The reason this is not Tower is because of the art image on the pillar which depicts the Yacht.
• Does not seem to have a real in-game location unlike the other ops

Ash Elite 2 art

• Oregon map, 1F, Rear Stage
• For whatever reason the art is a mirrored version of how it actually appears in-game
• 

Tachanka Lord skin art

• Kafe map, 3F, Piano Room
•
