Bit late out of the traps on this one, but I just rediscovered this title sequence that I made the art for in 2018, for 'Requiem', a major 6-part series on BBC1, directed by Mahalia Belo and starring Lydia Wilson.
I made several pictures and Peter Anderson Studios made them into this tidy 30-second opening sequence.
You can see and buy the screen and giclee prints of 'Requiem', 'Raven' and 'Moon Language' here.
