What are some yaoi manga that have pretty artwork? Usually it's very detailed artwork that I like

Some artists that I think draw beautiful artwork are:
PARK Sang Sun
YAMANE Ayano
OGASAWARA Uki
MARUYA Kae
YOO Ha jin
MARUYA Kae
MINAMI Haruka

Hana wa Saku ka by Hidaka Shoko <3

It's the Art of Time, it's the Art of Life--
Of the player and the craftsman,
Of the writer of songs, of the creator of love,
Of those who will follow, of those who led,
There's no other way in the world ahead ♥

Seriously this yaoi does not get the recognition it deserves. The first volume is absolutely amazing and features 2 pairings. Second volume however isn't as impressive, but you can still check it out. Beautiful artwork and some gorgeous character designs.

Deadlock by [a]Takashina Yuu[/m] - Very nice clean art. Ah, I just love clean art!
