I agree about Ogawa Chise (not too sure about Ougi Yuzuha, but I think the floaty hair is definitely similar).
lol All the characters sort of look like Tao from "Noblesse" because of their tall and thin bodies and hair.
I just realized I was actually thinking about nakamura asumiko when I mentioned ogawa chise, but yeah, hers is there as well. About ougi yuzuha, I guess it was the round, solid black pupils that reminded me of her. And maybe some parts where the necks were drawn thick. But it's especially the guy on the left in this page ( http://www.mangago.zone/read-manga/datte_oishii_no_ga_warui/mf/c001/4/ ) that reminded me of her work.
I could smell all the cigarette smoke while reading chapter one.
Also the art style to me looked like a mixture of ougi yuzuha's (just the face) and ogawa chise's.
