Oh yes Cry me a River ! I have enjoyed this story for the art too ! This author is also making Secondo Piatto, have you start reading it ? the characters are gorgeous ! _
in terms of art style, gorgeous art, that give me same vibe try Payback, Lost in the Cloud and Wet Sand. Oh yes , and Reunion and No Moral are very very good too.
And if you enjoy politic fiction go for Rainbow City, Blood Bank and Liveta. They all have excellent plots.
Also in the category Mystery*investigation*action type of BL, there is Breaking Through the Clouds and Poyun. I love the aesthetics and the work of shadows and lights in these comics. Speaking of this, one last title this one is a manhua and it's a gem ! It's called Antidote
But there are several comics with the same name so here is the link ! :-)
It's this one.

I have also enjoyed the artwork in Leo (lots of colours and interesting and unusual colour palette)
Historical could be BL or not BL, just anything with the same art style as Painter of the Night (by Byeonduck) puhleaseeee ┗( T﹏T )┛
