Nakamura Asumiko sensei's art is very unique and beautiful. If it's the art you especially liked you can try her other work. Although not all of them are tragedies.
If the requirements are just: 1) Yaoi 2) Tragedy 3) Manga
Then maybe these:

These one evoked similar feelings in me, although their artstyle is vastly different.

Thank you so much<3
Anyone know a yoai that's similar to Coponicus No Kokyuu (Yaoi)?
A yoai that's in black and white and tragic? Its doesn't specialty have to be the same plot, it also doesn't have to be placed in a circus, though I wouldn't mind if it was. Thanks^^
