Can’t identify the last one, so I’m safe. (Also not sure about some previous ones.)
Guesses
Left to right, top to bottom:
High wall of Lothric, first bonfire
Undead Settlement, by the first priest and bonfire
Archdragon Peak?
Church of the Deep?
Lothric Castle, above the dragons
Tutorial (Untended Graves)
Above Farron Swamp?
Ringed City, before the Halflight bossfight
Dreg Heap, where the tower falls
Catacombs of Carthus?
Archives, gank squad before Lothric/Lorian boss
???
Yeah, I consulted with a friend afterwards and he pointed out that what I said was above Farron swamp was Farron Keep Perimeter, where you find the Farron Coal and the twinblades. (Note: I did not tell him my answers, he got to ask but the last one on his own too.)
For the last one you are it right, tbh. I really have no idea on that one.
